Hi, I have a problem with one...possibly two, of my 7 week old goldfish fry. They are in a 30L tank with a heater set at 24°C. I have been feeding them baby brine shrimp, but a couple of weeks ago also started feeding them crushed dried daphnia and Liquifry No3. They have their tank vacuumed each day, when I change 60-70% of the water. A couple of weeks ago I was having issues with pH, and this led to an ammonia spike...this was rectified by adding crushed coral. They had been doing fine, although some were growing much faster than the others, and two of the bigger ones have now gone to live in the big boys tank. Sadly, the smallest one died...one minute he was swimming around just fine, and then a few minutes later his little body was stuck to the filter :( But I'm thinking maybe the ammonia spike was too much for him as he was very small compared to the others. Sadly one of them, Button (I have four remaining in the fry tank) has spent the last week lying on the bottom. He does try to swim about and manages to swim with a very zigzaggy motion, he'll swim up to the top and do a few loops of the tank, then sinks to the bottom, where he can't maintain a stable position. He usually ends up on his side, or on his head...poor little thing. I did take him out and put him in a separate box, but the water was getting so cold (my house is like a freezer!) and I don't have a spare heater or filter...or a spare socket, so I ended up putting him back in the fry tank. Now his little brother Seven has started to show the same signs...lying on his side on the bottom...although, he is still very active. I have continued to check the water daily...ammonia 0, nitrite 0, nitrates 5-10, pH 6.8 (still low, but much better than it was, and a stable 6.8 now). I've tried feeding him mashed peas (which my adult fish have every week and love them), but he didn't seem to know what to do with it. I've lowered the level of water in the tank, so he doesn't have to swim so high to reach the surface, and I've cut down on the food...but he's not getting any better after a full week now. Am I being cruel to him by leaving him like this, I keep looking at the clove oil, but he looks so determined when he's swimming I don't want to put him to sleep if he still has a chance of a happy life. Any other suggestions of what to do, or if it could be something other than a swimbladder disorder. Many thanks in advance.
Thank you, I've already ordered some more crushed coral as that is what helped with my main tank. I've always worried about adding bicarb as I didn't want to be constantly messing around with the pH, but you've convinced me now...and I think whatever happens it will be better for the poor fish than being in such unstable water conditions. A big thank you! :)
I noticed today that one of my 6 week old fry has one gill curled up, I didn't notice it yesterday and I check on them a lot. I do a daily vacuum of any fish poo and any leftover food, and also change 60% of their water. As they were unexpected it was a new tank set up and therefore wasn't cycled, so I added some plants from my main tank and some of the filter media and hoped that combined with the use of Prime it would be ok. I did notice a rise in ammonia and then nitrite, and finally was at 5.0 on the nitrates, and some days did two 70 % water changes to keep ammonia and nitrite levels down. After reading up on the cause of gill curl, I quickly did an ammonia test and was shocked that it was green and around 1.0! The nitrite was also at 0.50, and nitrates at around 5.0. I thought my tank was cycled about a week ago as everything seemed fine by then. I also did a pH test, I hadn't been doing them as I guess I was more focused on feeding, cleaning and checking other things. The pH was crazy, the colour in the container was bright yellow, and the lowest reading on the card is 6.0, and that is a lime green! I did have problems with my main tank, my tap water is 7.4, but within an hour of being in the tank was dropping to 6.2!! I tried adding more rocks, and eventually tried crushed coral in the filter, which worked and things settled down. But this is even worse! I have a doctorate in molecular biology and I'm at a complete loss as to how water can drop from 7.4 to below 6.0 in an empty glass tank! The only things in there are the filter, heater, and some anacharis from the main tank. I've just added some rocks from the main tank in the hope it will help, but I'm utterly confused! I assume that the low pH must have caused the death/dormancy of the bacteria that had established as I can't see why else I have such high ammonia levels. I tested the pH with the Prime and that actually raised the pH to 7.8, so it's actually a drop from 7.8 to down below 6.0 within an hour...my poor little grandfish! And my poor Obi (the biggest fry) and his folded back gill...any advice will be gratefully received! Thank you!
Hi, six weeks on from the birth of my unexpected fry and all is looking good...although I did lose one last week, he was the smallest and although he looked ok, I guess he wasn't doing so well...poor little chap. Anyhow, the largest is an inch long and looks like a monster compared to the others! Two are about three quarters of an inch long, and two of the remaining three are just over half an inch, with the smallest just a tad shorter...these three are also quite skinny although they seem lively and well. I'm surprised at the difference in sizes as they were all pretty much the same up until week four when Obi, the largest had a sudden growth spurt and doubled in size that week and again the week after. Button and Weirdo (he's such an odd, grumpy looking little thing) also had obvious growth, but Seven, Fry and Pumpkin only grew a little...and haven't shown any significant growth for the past two weeks. They all have all their fins nicely developed, and have started to develop colour patterns...the only difference is the size. They're at 24°C, have a 60% water change daily, when I also remove all the uneaten food from the bottom of the tank. And they're fed BBS, crushed dried daphnia and Liquifry 3 Baby Plus, they have a selection of these 5-6 times a day. For the first month they had only BBS. Is it normal for such a huge difference in size, or am I doing something wrong? I realise that most breeders would have culled the tiddlers...but they're my grandfish :) Any advice welcome...worried that as Obi continues to grow he may soon be able to eat the smaller ones! Although, he can go in the big boy's tank when he's a little bigger :)
Hi Fishlady, thank you for the advice. You could be right, I keep them at around 20°C, but I put the heating on each evening, which is set at 22°C. Most days my thermostat says around 14°C when I get up and it tends to stay that way all day...so I guess that could also be lowering the temp in the tank during the day, even with the heater on, as it is very cold in this house. I think I'll have to just leave any new fry...but it'll be hard to do. But yes, better for the other fish in the long run. Thanks again. Have a good week.
Hi all, a couple of weeks ago I was doing my weekly water change when I noticed some strange little alien things clinging to the sides of the tank...after realising these funny little things were my grandfish, I syphoned up as many as I could and then sifted through the buckets to save them. I only managed 7 as they're fast swimmers...or fast wrigglers...and hid amongst the plants and gravel as soon as the scary hose was near them (I would too!). I set up a spare tank and rushed out to buy some liquid fry food and instant baby brine shrimp, and two weeks later they've more than doubled in size and actually look like fish now. They seem to be doing well. I change 20% of the water each day, have a sponge filter and the heater is set st 26°C. I also put some anacharis and anubias in from my main tank. Anything else I should be doing? My main concern is my adult fish...I have 2 females, although one is only about 9 months old and the eldest is around 15 months. I noticed the first breeding activity back in April, and they ate the eggs straight away, and every time I saw them chasing around, I never noticed any eggs attached to plants or anything. The thing is, that my poor female is being chased about every three to four weeks and now that the eggs are hatching and I have fry, I'm a bit worried. Do they usually spawn so regularly? And is it safe for her, she seems happy enough, but looks exhausted at times, and the youngest male (9 months) has just started joining in too, so she has three to deal with. I don't really have the space for any grandfish...although I can't bear the thought of giving them away to anyone who I wasn't convinced would care for them properly. Is there anything I can do to reduce the 'sexy time' :) As I'm glad they're happy, but I'm too young to have anymore grandfish! They have a heated tank, it's set at 20°C, and obviously rises with room temperature in the hotter months, but my house is generally cold, hence the heater.
Re: Fish darting, scratching and fin flicking...
Hi, thank you for your reply. I was hoping it was just something they'd stop doing, but they're scratching at least once every hour, so sadly it's not just occasionally. I'm glad you think I'm taking good care of them, as I really do try to keep them happy and healthy, so that makes me feel a little better. I guess I'll just keep an eye on them and see if they get any worse, although I'm hoping it will soon stop and go back to normal as they have me really worried about them. Thanks again :)
Hi, I posted a couple of months ago about this issue. I'd recently bought a new fish and it was suggested I treat for gill flukes, which I did. I contacted the company that made the medication and was advised by one of their chemists to double dose for 12 days. I did this and it made no difference. I left it for a week and then treated for bacterial infection as advised to do following the other meds. It's now over a month later and they are still scratching, darting about and flicking their fins. They still have no obvious signs of disease, no red streaks or ragged fins. No clamped fins or gasping. Their gills look fine, they have no white spots or any other tell tale sign...they look happy and healthy other than the scratching. I test the water every few days and it is always 0 ammonia, 0 nitrite and is always between 10-20 nitrates. After adding coral to the filter I now have a nice steady pH of 7.6. And GH is 8°d, KH is 6°d. I recently tried a King British disease clear, and then Interpet disease treatment...both did nothing. I hate to keep trying different medications, but I have no idea what is wrong with them. I even bought new test kits to check my results and I get the same readings (API and Pondlab liquid tests). I've always used the same water conditioner, so I can't imagine that would be a problem. They have a 30% water change every week with a good gravel clean, and once a month I like to change 50% of the water just to give it a good clean...although their water is always clear and smells earthy rather than nasty. They have a varied diet of Hikari pellets, dried daphnia and bloodworm, peas, spinach, broccoli and cucumber, plenty of plants to swim about in and eat, a constant temperature of 22°C in the summer (I slowly drop it down to 18°C in the winter). They are very active, friendly fish. They love being hand fed and they do that cute wiggle when I walk through the door and they see me...but this is worrying me and I really want to help them. Any other ideas?
Hey guys, I want to build a pond in my garden but am unable to have any electricity available to run a filter/pump. I'm hoping to rehome my goldfish once they reach 5-6 inches as I want them to have lots of space ( I currently have a 3.5" and two 2.5" fish in a 4ft long 250L tank). Does anyone know if there is anything available that could run from a 12V battery or similar. I know there are solar ones available...but I'd like something more reliable. Or does anyone have experience of keeping happy healthy fish in a natural pond? Thanks :)
