Why can't I keep fish alive...

[findingnemo1]

What about your oxygen levels? Do you have enough powerheads and water movement at the top of the water? Maybe youare not getting enough gas exchange and they are suffocating. When do they die? At night or day?

I'd recommend seeing if the LFS will allow you to place a deposit on the fish, then let them stay at the store for a week before you bring them home for quarantine. Sometimes the brand new arivals at the LFS are experiencing lots of trauma from shipping and need a bit of extra time to recover before they're shipped a second time to a tank at your house.

Plus, it's better for it to die a day later at the LFS, than a tank at your house. Takes yourself out of the equation in it's death, and saves you money. Most places will let you re-apply the deposit to another fish.

You need to give us a bit more information. And don't always trust a test kit. Borrow or buy a different brand for ammonia and try that. What kind of water are you using. What sort of symptoms do the fish show before they die.
Check your RO filters. Are they clogged and letting chlorine and other chemicals in.
Do a chlorine test.
Hope some of this helps

Is it just new fish that die or all fish in the tank? Also what other livestock is in there? As this is in the reef forum, I was curious if you had corals ect that were doing better than your fish stock.

Hey, I just read apost of yours in this thread http://www.canreef.com/vbulletin/sho...575#post240575 where you did a expanding styrofoam backdrop using krylon paint. As far as I know none of this stuff isn't made for marine use and who knows if it's safe for your livestock. You could be poisoning your fish.

Edit #2
I very highly suspect this is killing your fish. Just looked up the ingredients of kylon fusion paint. Here see for yourself. http://www.paintdocs.com/webmsds/web...C=724504025184

OY! That can't be good.

[X-Treme]

One other thing to look at.......when the fish "die" are they still in the tank (meaning can you see the dead body) or do they just disappear? (here one day, gone the next) If the latter is the case, maybe you have a mantis shrimp????

Holy carcinogens Batman!!

[AndyL]

krylons proven itself to be safe in reef tanks... there are hundreds of tanks out there with significant amounts of painted material... Including mine; never had unexplainable deaths (fish or coral).

I notice most of those carcinogens etc are part of the propellant & thinners (things which once dry are gone). MSDS requires some skill in interpreting - doesn't tell you everything. Should we dig out the MSDS on de-ionized water - I've got a copy at work!

[justinl]

tell us about your tank. dimensions, filtration, livestock, powereheads, heaters? parameters, livestock, LR, sand?

Are the fish you're trying out just the kind of fish that don't do well, like moorish idols?

yeah i agree that the foam might definitely be a cause.

[Black Phantom]

Scary - the foam back was the thread I started. I think I'll stick with the natural look.
