Keeping the Community
So recently my community has taken a turn for the worse. I have been focusing on my plants and the new lighting I received. The other day I noticed that my gloBarb (Yes I know they are "Aggressive" but he has never shown a single bit of it. He used to be in a tank with other barbs and they used to beat the crap out of him and he would hide.) had been attacked. I immediately pulled him out of the 30g and put him into a 3.5 gallon hospital tank and have been dosing him with stress coat.
I do not see how it can be from tank related sickness since my parameters are not harmful and I did see what appeared to be damage on his outside. He is also swimming a little awkwardly at the moment, I don't know If its from the tank size or injury.
That night I also found on of my larger White Skirt Tetra dead at the top of the water. (from earlier in the day death)
The next problem is that this morning when I woke I noticed one of my Bolivian Rams eyes looked a little awkward and had a little bit of red under it.
I cannot figure out what is causing this because I never see it. The only thing that can come to mind is that about a month ago my little LFS sold me a "Skunk Loach" to remove the snail parasite I have in my tank. Recently I discovered that they are actually a very aggressive fish.
If its not that I added a school of neon tetras into the tank a couple weeks ago. I have never heard of these fish causing this kind of problem though.
What steps should I take next?
