Mysterious dying? (Tiger Barbs)
I've had three tiger barbs in a 10g for a little over a month now. I realize that the preferred tank size is 30g+ for tiger barbs, but I didn't want to upgrade too fast until I was comfortable with the species.. and then I wake up this morning to find one of them had died. No bite marks or anything, so I figure he wasn't attacked by the other two.. (he wasn't very small either) and the water is kinda murky, despite the filter, I guess because of the presence of dead fish. Now the other two are acting kinda mopey and I'm wondering if I did something wrong. Night before last I did a 50% change and added gravel and an airstone. Their food is flakes and tends to float to the bottom. Any chance my critter mistook some gravel for flakes? Or the airstone didn't agree with them? Up until the change the critters were doing fine, schooling, swimming about, eating. I didn't think it was the water because they'd been fine with it for a while now. The gravel I added is the kind I use in my other tanks, which usually settles just fine.. I don't know. :(
