Re: Devastated my lovely 7 year old goldfish died this morning
Sorry for not replying before now, and even sorrier to read of this sad situation - I empathise wholeheartedly, as I know very well how attached it is possible to become to goldfish.
Have you any idea at all what caused the ammonia spike? Had it been fine the previous week or did you miss out testing for a week or two? Did you change/remove any filter media at all? Did you put the pure aquarium balls in the filter to address the ammonia spike or did the ammonia spike occur alongside/after this? [For peace of mind, you could always contact your water company and find out if they had a problem around that date eg I learned that there was a problem with the local supply for a day or two where I live but unfortunately I had already done a water change a few days beforehand.]
What size of tank was she in, and what size of water changes did you do weekly? When you cleaned the stones/substrate, how did you do that? Do you know what your water hardness and PH is? Your water company website should be able to tell you these, the former in German degrees hardness and CaCO3 - let us know the results. [There are a few theories I have but your answers to these might help work out the possible cause.]
Did you happen to test the water after putting in the Seachem Stability? It does seem as though that had a catastrophic effect at the end, sadly, but may have compounded an already precarious situation.
If you don't mind / it's not too painful for you to answer these questions, then it might help us either put your mind at rest over some of them or work out the likely cause if indeed we can identify that.
That is possible or she may have a bloating condition. [In my own case, I have an elderly tetra who had eye damage from spats with his shoalmates and this eye is extremely distended - but he's been living perfectly well with it for the past year.]
If I were you, I'd increase the weekly water change to at least 30% (anything up to 50% is fine). If there are no other problems or changes in behaviour, then that should suffice. If there are further problems or changes in behaviour (whether or not post-birth), then we can advise further on any action to take.
The Fluval Roma 240-litre, Eheim Vivaline 240-litre or Juwel Rio 240-litre tanks are long-length ones for their volume and so are ideal for goldfish, as well as these being reputable brands - go for this size at the very minimum (and do not be tempted to add any more fish even if they seem small in their environment to begin with). You might get some more inspiration, plus further ideas for larger tanks, from here https://www.completeaquatics.co.uk/aqu ... uarium-tanks-and-cabinets
It might be worth getting some eSHa 2000 too - this is a great medication for finrot and fungal conditions and can be used in tandem with eSHa Exit for stubborn conditions that aren't clear whether they are ich/whitespot +/- finrot.
In the meantime, daily water changes of ~50% ought to help considerably too.
Thank you for your reply! The fish are quite young and small, that’s why i thought to put them in a tank of this size until they got a little bigger, but i was wrong. I’ll definitely be upgrading the size of my tank as soon as possible!
I ordered a water test and esha exit online a few days ago and they should be here soon! I have done an extra water change and added some benifical bacteria, along with increasing aeration in the tank. I had a feeling the tank was to small and will definitely upgrade it. What size do you recommend? Unfortunately my black goldfish passed this morning so now it’s just the three left:( The shubunkin seems to have less spots but there are still a few. How do i treat the blood streaks or will they heal as I make adaptations? Thank you so much for the reply!!
Either a 10-minute dip in a weak potassium permanganate solution or in a weak bleach solution (dilute1:20). Follow with a good rinse and for the bleach, a soak in water with a double dose of dechlorinator.
First, do you have a test kit? If so please post test results for ammonia, nitrite and nitrate. The bloody streaks are common where there is ammonia and/or nitrite in the water. Secondly, it sounds like they have white spot - treat this with Esha Exit.
The bad news is that the cause of this is that your tank is much too small - it's not even big enough for one goldfish. The minimum for a single fancy goldfish (fantails, black moor etc) is 140 litre plus 40 litres more for every additional fish. For single tails like the shubunkin it needs to be even bigger. This article explains: https://www.fishkeeping.co.uk/articles ... -size-life-expectancy.htm
my black goldfish has prominent white spots and clamped fins. My shubunkin has a quite a few white spots too but also what i assume to be a streak of blood in his tail. is this fin rot? Ick? My other fish seem to be healthy. My tank is about 22L and i use water conditioner and beneficial bacterial for my tap water, I clean it out roughly once a week. The hang on filter gets cleaned every month or so. I also have some duckweed in my aquarium and feed sinking pellets three times a day usually. Any help would be greatly appreciated as i am new to this!
Hi all and my apologies if this has been asked before.
I'm planning to buy some new Java Moss and Java Fern plants and wanted to know if there is anything I can soak them in first to avoid snail infestation. This was something I didn't do the last time I bought them (from my LFS) and I wound up with snails everywhere which were a massive headache to eradicate. Any advice would be much appreciated
