jude Posted May 24, 2006 Report Share Posted May 24, 2006 And before you ask, no I haven't tested for anything :lol: :lol: This is my little fishtank at work. I think it holds about 25 litres. I noticed it seemed smelly the other day so did a 25% water change. I checked today and it really stank. It has 4 or 5 cardinals and 5 harlequin tetras in it and I had added 4 small clown loaches to get rid of the snail problem. It has a built in filter at the top of the tank and the sponge was disgusting and stank. I have rinsed the sponge out and removed the clown loaches because they've done their job, and because they might have been overloading the tank. I also did another 25% water change but it still seemed a bit whiffy to me. It has a thin sand base and quite a few plants for a tank that size and its been running smoothly for several months now. Any suggestions as to what might be causing it and what else I could do about it? The water looks crystal clear although I know thats not an indication of its quality.

jude Posted May 25, 2006 Author Report Share Posted May 25, 2006 Hard to describe - it smells bad/rotten Quote Link to comment Share on other sites More sharing options...
Wok Posted May 25, 2006 Report Share Posted May 25, 2006 a sock? Underarm..? dad fish blue green algae? If you can wait till the end of next week I am sure you will have a lot of experts to look at the situation Because the fnzas conference is in Upper Hutt Next week. We can all go down and sniff it for ourselves :lol: Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 25, 2006 Report Share Posted May 25, 2006 Most likely is a rotting body stuck somewhere. Perhaps a fish died then got sucked into the filter and has slowly decomposed in there? Quote Link to comment Share on other sites More sharing options...
Pegasus Posted May 25, 2006 Report Share Posted May 25, 2006 Also look under rocks.. ornaments.. or other fixtures for patches of gravel that have turned black.. (usually very smelly.. anorobic bacteria) due to decomposing food.. or perhaps a dead fish. You may have disturbed some of it during a water change with the siphon. Bill.

jude Posted May 25, 2006 Author Report Share Posted May 25, 2006 Ummmm I don't think there are any dead fish but I will take everything out tomorrow to check- my receptionist counts them every morning - she's fascinated by the tank. When I arrive at work I get a report on how many there are and if they are doing anything unusual. There is only a very thin layer of sand and no black areas that I can remember but I will have another good look and I will take everything out to see if I can find a body somewhere. There's no ornaments apart from a small piece of driftwood with java fern on it and it smells ok. I took all the rocks out about a week ago so the snails couldn't hide from the loaches ...... :lol: The fish look ok at this stage but there's definitely something wrong in there Thanks everyone Jude Quote Link to comment Share on other sites More sharing options...
Modern Angl Posted May 25, 2006 Report Share Posted May 25, 2006 Possible dead something jammed in filter? Had a thought it could be dead snails stuck in there to get away from the loaches... Quote Link to comment Share on other sites More sharing options...
jude Posted May 25, 2006 Author Report Share Posted May 25, 2006 LOL - good thought. I will check for lemming snails tomorrow Quote Link to comment Share on other sites More sharing options...
Keri Anne Posted May 25, 2006 Report Share Posted May 25, 2006 Witha tank that small it's also easy to over feed... Check that your receptionist isn't sneaking then extras. I discovered that my flatmates was doing this "Because they looked hungry" lost a few fish before I discovered the issue. Quote Link to comment Share on other sites More sharing options...
jude Posted May 25, 2006 Author Report Share Posted May 25, 2006 Another good point Keri - she is pretty good but she loves to feed them so that might be the problem Cheers Jude Quote Link to comment Share on other sites More sharing options...
sharn Posted May 25, 2006 Report Share Posted May 25, 2006 you dont feed them shrimp pellets do you? my first thoughts were the food or anerobic bacteria, that smells like sulfur *holds nose* when was the last time you cleaned the filter out? perhaps it was just so gunky it was stinking everything out and now it might clear up?
