Hello,

This really does look like a neat site. I found it after I got my ripsaw catfish, but it's a shame that my first post here has to be about his death.

I have a 55gal tank with two silver dollars, two small freshwater puffers, a spotted raphael and a royal pleco. I do water changes every 1-1.5 weeks and my nitrate count is as close to zero as I can keep it. I have an Eheim wet/dry cannister filter (I forget the model number...it's big).

When I visited my local fish store for food, I saw the ripsaw. My wife and I keep seeing cats that we really like, but are used to hearing the same thing, that the fish we like will eat everything else in our tank. We expected to hear the same thing about the ripsaw, but the owner of the store told us that they were pretty docile, very intelligent fish.

I took him home and was delighted to add him to my tank. In 24 hours, though, he was dead, and very suddenly. The first 12 hours, he mostly sat in a corner and hid. After that he was what I would describe as 'listless.' He would swim for a bit, even near the top, then stop and drift to the bottom, settling on whatever he drifted onto. I checked on him about every 15 minutes after work the next evening. Suddenly he was just dead, stiff as a board.

This is not the first time this has happened. A couple months ago, I bought a king tiger pleco, who lived about a week but died very much in the same way. I didn't see the same listless behavior that I did in the ripsaw, but he was rigid like glass when I removed him from the tank.

Before the 55gal, I had a 28gal bowfront. I tried to keep a striped raphael in the tank twice, but both died much like the ripsaw, within about a week. Despite being nocturnal fish who like to hide all day, they sat on the top of plants and rocks until they died.

As I said, I have two other catfish in the tank, the royal and the spotted raphael, who seem to be fine. I've had both for over a year. They hide all day, but are very healthy.

If anybody has any suggestions, I'd be glad to hear them. My local fish store owner tells me I probably have a buildup of hydrogen sulfide in the tank, so I should remove most of my substrate. Right now it's a couple inches thick, but I stir it up when I siphon every week. I thought that would be enough to keep anaerobic bacteria at bay.

Thanks.
 
Hey, welcome to the site. How long have you had the tank and how long has it been running with your fish. The reason I'm asking is because the water in the tank needs to be cycled before adding any permanent fish. You can use the search button for "cycle" and you will get many ways to do it and why. I'm not sure what killed your catfish but I think the first thing you might want to do is to test your water. Also, freshwater puffers aren't really freshwater. The require brackish water (water with a salinity between fresh and saltwater. Again, welcome aboard and feel free to post any questions, The Doctor.
 
Thanks for the reply. The tank has been running since early March. I cycled it thoroughly before moving my fish, a couple at a time over a period of a couple weeks, from the old tank to the current one. My puffers are, in fact, freshwater fish. There are marine, brackish and freshwater species. The Shedd Aquarium in Chicago even has freshwater puffers - although (like all of their South American fish) they are *much* larger than mine. I test my water at least once a week, usually more. I normally use strips, but if I want to keep an eye on something specific I use a test kit for that chemical. My pH is neutral and (as I said in my earlier post) my nitrates are as close to zero as I can keep them. Last night when I did a water change I removed at least 50% of my gravel. There is an average of about 1" in the tank now. I saw no bubbles when I vacuumed it last night before I removed it, so if I do have a hydrogen sulfide problem it is very early. I condition my water with stress coat before putting it in the tank. I have never seen any chlorine or chloramines in my water and the pH tends to stay very stable.

Wow, I apologize for the single, huge paragraph. When I hit 'submit,' all my formatting went away.


I don't believe stress coat actually contains anything to get rid of chlorine or chloramines. Also, I didn't know there was a kit to measure chlorine or chloramines. There have been many people on this site who had the same problem as you with fish dying. They ended up finding out that their water dept. started adding chloramines. If you're positive you don't have chlorine or chloramines than I don't really know what's happening. However, if your 100% positive the water doesn't contain any of the 2 chemicals, that buy some appropiate conditioner. The price of the conditioner will be a lot less than what you will be spending on the dying fish. Hope this helps, The Doctor.

P.S. I looked up freshwater puffers and you're correct. There are some that live in freshwater. You learn something new everyday.
 
could be huge ammonia spike from removing gravel and all that jazz

stress coat does remove chlorine.. if it didn't his other fish would be dead too...

what temp is you tank set at??



What about the more dangerous chloramine?
