DEAD Fish!!!!!!!!!!?

Question

I had 2 neon dwarf gouramis in a 10 gal tank. I have live plants, real nice set up, filters, bubble curtain, etc. I tested the water every other day, Nitrate and nitrite levels were at 0, ph was at 6.8, and ammonia was at .25 (then I added a little ammo lock so the small amoutn of ammonia wouldn't hurt the fish), so that was alright. I came home to find one fish dead, chillin on the bottom of the tank, without any signs of injury. Where did I go wrong? And what do I need to do so the other fish, and any new fish I get don't get infected with whatever the dead fish left behind?

Oh, and I only had the fish for about a week.

Answer 1

Note that even .25 is a lot of ammonia for some fish. Dwarfs are not the most hardy of fish, and not a good 1st fish for a tank. If there is no sign of swelling, or extrenal infection you just need to keep on eye on the ammonia. Avoid adding another fish for at least a week, and until ammonia levels stop spiking. If you do want to add another fish consider a guppy, or female betta (avoid males as he might take it into his head that the dwarf was a betta). With a small tank like a 10 gallon I'd avoid dwarf gouramis until the tank establishes a good nitrogen cycle.

Answer 2

Doesn't sound like the tank was cycled. You have the right idea with the test kits, but ammonia and nitrites should be 0. When you start seeing nitrates and 0 on the others, you'll know it's cycled. Even small amounts of ammonia can kill fish. Don't add any new fish, and when you do, do it slowly-just one or two at a time. If the fish is still alive, do small water changes everyday till the tank is cycled. I'd consider taking the live fish back though. Maybe you could ask the petstore for some "bacteria" from one of their tanks to speed up your tank cycling.

Answer 3

Dwarf gouramis are not very hardy and it probably died just from the transfer shock. Did you introduce them very gradually? Did you avoid putting water from the store into your tank? Were they eating well?

Don't get any new fish for at least a few weeks when you can be sure the remaining fish is stable ... then add only one or two at a time. things can go wrong fast in a small aquarium like that.

Answer 4

you need to cycle your tank properly and change 10-15% of the water every few days also what could have killed it was the Ammonia lock an unnecessary chemical

Answer 5

I also bought gouramis few days ago. But no luck. All gouramis dead. All other fish are ok, but no gourami in my tank :((

Answer 6

It's hard to say, how was it acting before it died, was it eating, did it gasp for air at the water surface, was it trying to scratch against rocks or gravel?
