Agressive Blue Gourami

[uaelove]

Hey guys,

I'm new to this forum and to the freshwater tanks world :)

I have a 29 Gal, platies, mollies, guppy, etc., and my gourami is the opaline/blue one. I have 2 of them and and just added a male dwarf.

So, the problem is one of them looks happy (because it is dark in color and hangs from mid to top of the tank) while the other two are not (more pale). Also, the unhappy ones are always at the bottom and like to be hidden behind/in objects/plants in the tank. One more observation, the happy one likes to chase the other unhappy ones?? I don't know what to do and why one is happy and the others not???

I moved the agressive one of the tank then the other blue acted the same to the new male??!

Thanks guys in advance..

A 29 gallon is far too small for more than one gourami as you describe. Please try to rehome two of them and only keep a single specimen.
