your 10g tank is waaaay overstocked
The fish are all quite small, especially two of the mollies. (They're fry) one angelfish and all the mollies are going to be taken out and given to the
lfs or one of my friends, but I can't do anything with them right now.
Uhm... maybe you didn't add dechorinator enough?
Nope, did all enough of that for sure! I've lost fish that way before and so I've learned that heard way...
try a few 30% water changes, one a couple of hours after the first, then another four hours after the first.....and make sure your filter is working well and is not full of detritus.
I got on here last night and typed this whole huge post about what has happened with the tank in the past few days, and then the power went out and of course the computer crashed! But anyway, the other day I went to the
lfs that will test water that is incidentally located halfway across the globe from my house) and had some water tested again (3 days ago). They said my ammonia was waaaay high again. So I did a 50% water change, thinking ehy, if this happened last week mybe that is why my fish are acting strange. But this is when it all started happening just like last time. Maybe sudden good improvements shock fish- anyone have that experience?
So then the whole thing with the tempertaure rising to 84 when it's normally 77-78 (I realize most of you keep your aquariums in the low 80s and it's not high, but my fish aren't used to that) really just hightened my concern.
I did what a couple
fo you suggested and added an airstone from one of my existing tanks... it seemed to help for a little while, but...
The issue now seems to be the light. I have two 15w white, incadescent bulbs. They've been on the tank for the entirety of it's use. But now my fish seem to have a problem with it. When the light's off they all swim in their normal levels (barbs high, angels mid, puffer low) but when the light is ON they all stay on the bottom and turn pale.
I tried something last night. I took one of the bulbs out and put the hood on. The fish all congregated in the dark side and seemed fine. But with both lights on they stay on the bottom. What could be causing their sudden fear of light? This is the same lighting they've all had from the moment they went into the tank. 8O
