i have 2 betta tanks, they r both 1 gallon, i put the together side by side. is it ok?
will my bettas get injury by hitting themselves onto the glass? will they build bubble nest like this?
TLD unless those bettas are really trying to kill each other i don't think that they would hurt themselves but, just to be on the safe side i would move them away. They wouldn't build a bubblenest because that is for the eggs and for a spawning site since you have two males they wouldn'tbecause you would need a female.HTH ;D 8)
If they start beating themselves up on the glass trying to get to each other why not put a sheet of translucent plastic between the two tanks so they can't see each other quite so clearly. Just a thought...... 8)
