Hi everyone this is my first post here. Yesterday I bought two Tiger Barbs and two Albino Barbs for my 10 gallon tank. OK so at first everyone was going well but soon the two Tiger's and one of the Albino's started swimming together and left the other Albino all by himself at the opposite end of the tank. When it came time to feed them he waited in the plants until the other three fish left to come out and grab some food. Now simple logic says they're probably bullying him, but now I'm starting to worry maybe he's sick. These are my first fish so I wanted to check here before I add anymore fish or take the one Albino out. Oh and the waters pH is 7.2 and the temperature is 78 degress. Thanks.
