Haven't managed to get test kits yet my local pet shop was sold out and I don't fancy driving 20 miles to Pets At Home while the roads are icy, so I'm going to have a look online. My dad isn't sure about the idea of rehoming some of the fish, as he rightly pointed out we're not losing fish and they all seem healthy. But we'll decide what to do when we see what the tests say.
Just checked water quality on Severn Trent, apparently it's moderately soft (german degrees 4), and the pH is 7.69. So softwater fish should be OK. I'm planning on doing a partial water change tomorrow, is it best to carry out the tests on the tank water before this?
At the moment I make it just over 200cm in total. So I'm definitely going to have to rehome a few. I'm not sure where I can find homes for them yet, and I don't intend to get a second tank. I'll have to think about that one. Which ones should I consider finding homes for? The water temperature is around 25 degrees. I can't give an exact figure for hardness, but I know it's pretty hard around here. I imagine the pH is fairly high, being hard water, but again I'm not sure of an exact figure. I'll see if I can get some test kits tomorrow and post the relevant info. I must admit it doesn't look crowded at all, and I'm thinking my plants may have something to do with this. A couple of them are getting quite large, so things may look a little different after some heavy pruning.
Thanks for the replies guys. I don't think the overstocking quite as dramatic as that. I'm not saying it's not overstocked, by the sound of things it is. Your calculations are based on the maximum sizes of the fish, but many of my fish are nowhere near that size. My gold sucking loach for example is not much more than 10cm and seems to have stopped growing now. I'll try and work out how much length of fish I've actually got in there. I'm not saying you're wrong, if the recommended stocking density is 5cm per 4.5l I'm definitely overstocked, but I'm thinking when I work it out it may be more like 2 or maybe 3 times. Just goes to show that you can't believe everything you read, the website I went to in order to work out my tank's stocking capacity said it should be able to support 56 full-bodied fish or 92 slender fish. I probably should have got a second and maybe third opinion first. Oh well, I guess I've still got a lot to learn. Thanks for the advice!
Hi Violet, thanks for replying. In answer to your questions:
My tank is approximately 100 litres, 80cmx35cmx40cm. My filter is an Aquael FAN-2 plus, output 450l/h, this was the filter supplied with the tank. Fish - I currently have 56 fish, I know this may be a little overstocked perhaps but it seems to depend where you ask. Breeds and numbers: 9 neon tetra, 3 glowlight tetra, 2 black neon tetra, 2 peruvian blue tetra, 1 octocinclus, 3 platys, 3 rummy nose tetra, 1 scissortail rasbora, 2 red honey gouramis, 3 cherry barbs, 3 black widow tetra, 2 swordtails, 4 zebra danios, 1 gold sucking loach, 2 peppered corydoras, 1 molly, 2 red tailed black sharks, 3 bengal loaches, 3 purple harlequin rasboras, 3 bleeding heart tetra, 4 glass catfish. I do a 20% partial water change once a week. Water conditioner - I use Tetra AquaSafe. I'll buy the relevant test kits over the next couple of days and post the readings. The water doesn't seem to be green, the water I take out when I do a partial water change is yellowish, presumably this is from fish waste? The cloudiness is more whitish I guess, so bacteria then.
Hi, my name's James and I'm fairly new to fishkeeping. I've always liked fish but it wasn't until last year that I decided to get an aquarium. It's been a bit of a learning curve, wherever possible I do my research before I buy a fish, following a mistake fairly early on (when I bought two red tailed black sharks I wasn't told in the shop that they were likely to attack each other). But I'm really enjoying it as a hobby and I don't know why I didn't do it before. I'm still coming across a few things I'm not sure about so hopefully some of you might be able to help me out.
Hey, I'm new here, wondering if anyone can help with this problem. I'm fairly new to fishkeeping, got my first tank in September. Over the past few weeks the water has been a bit cloudy. It's happened before but it usually clears up after a day or two, failing that a partial water change makes a difference. But this time it's been like it a couple of weeks and partial water changes haven't made any difference. Any ideas? I haven't tested the water quality but there doesn't seem to be any problem on that front, all the fish are fine, I've even got glass catfish in there which are happy and healthy. Judging by what I've read about them, they'll be the first to go down if there's anything wrong. Can anyone tell what could be causing it and what to do about it?
