A few weeks ago I lost a peppered cory from my tank, I found it unusual, but did not think much of it as it appeared to be only one. I don't know what happened to it, as my tank is heavily planted, and by the time I found it much of it was gone. Then, a week or so ago I noticed another acted odd, laying on its side, breathing slowly. This one was one of my oldest cories, so I figured probably old age (this one is at least 4 years old). While he is still alive, I noticed one of my smaller ones acting in the same way. Laying on its side, shallow breathing, then swims off a bit, before stopping and laying on its side.
Everything else in the tank is fine, there are fish in there that (IMO) are nowhere near as hardy as the peppered cory, and do not appear affected (Angels, Otos, Black and Regular Neons). There are no new inhabitants in the tank, the only newest addition was some plants (which had snail hitch hikers) but they are also in another tank, and the fish in the second tank are also doing fine.
So, what is happening with my cories? I will try to monitor them, but so far the only symptoms I see is listlessness and laying on their sides, they are not laying straight though, but curled a little. I should add though that they are swimming fine, its just when they stop they are not straight.
Any ideas? Thanks.
