i originally bought 3 rbp's, all about 1/2 inch in size. after my latest water change and gravel cleaning, which ended up being about a 60% water change because i had some trouble operating my gravel cleaner and hosed to much water out of the tank, the fish started reacting poorly, and being quite skittish, i immediately assumed this was just him getting reaquainted. from day one he was the odd one out and the other 2 stuck together. but up until the last water change they never bothered him, they started to bite at him after this last water change and then today i found him dead in the tank sitting upside down in the gravel at the bottom with some pretty big chunks out of his back fin. do you think this is just as a result of stress and the other two are ok, or should i be concerned the other two will share the same fate. here are some pics of the dead rbp. thanks sad.gif
the other two are still fine and acting as they did before the water change, this was the only one who acted differently.
