Tank: 20 gallons
Been running since last June
AC 200 filter
Handfuls of hornwort, some strands a foot long Shocked
Some java moss

Other life: 2 mollies (one of them a balloon, both female), 3 albino cories, 2 bristlenose plecos (one going to an lfs next week).

A few days ago, the golden wonder killifish that resided in the tank died. I suspect the cause was the now gone male molly picking on it. On the same day, I did a 25% water change.

Now, I'm worried about one of my cories: it leans on its side, almost lying down on its side sometimes, and doesn't move much save to breathe. When I act to net it, it springs up and takes off. Okay, thinks I, this does not seem to be a common cory game. What gives?

On Wednesday, when I removed the male molly (and the killifish died), I removed a tree-branch ornament; there's a hole in the bottom of said ornament, and the foulest reek stench came from the hole as I rinsed the ornament off. I rinsed it several times, filled and emptied the hole, and the smell diminished. It smelled like bad water, like burnt something as well!

Today I noticed another cory leaning to its side, springing up and away when I get the net. Also, my balloon molly female was dangerously almost floating on one side near the top of the water level.

WHAT is going on????

(tests done 30 mins ago)
Ammonia: 0
Nitrite: 0
Nitrate: 30ppm
Cl: 0
pH: 8.4

don't know for sure what the problem id, but if you suspect the branch, take it out! and start doing some daily water changes until you see differenet behavior

I find that the reptile ornaments are too near the fish ornaments in some stores. It may not have been considered "fish safe" in the first place. The branch is rotting and/or releasing foul things.

Get rid of it at once, do large water changes.

I took the branch out last night....no more leaning cories, but the balloon molly still has me worried. I'm not sure if I bought a weak fish, or what, but she still hides in the floating hornwort, and looks dead.

Sounds to me like the branch created an anaerobic area in your tank. The hole in the bottom of the branch was an area where there was probably no water movement. Maybe someone else can explain the dangers of anaerobic 'dead spots' in aquaria. Did you do a large water change after removing the branch? That's what I would do.

The odd thing was that this hole, at the bottom of the ornament, was actually NOT in the gravel; I had tipped the ornament on its side, and the hole was exposed to the tank overall, plus plants and filtration.

Hmmm.

I don't think that the hole would have to have been in the gravel to create anaerobic conditions. The wood itself, if it is rotting and depending on it's own porosity, could still become anaerobic without having to be buried. Even though the hole was exposed, unless it was directly in the path of some current or a favorite hiding place of some fish, there would have been little water movement in there.
