Not a real emergency and I am not sure if it is really a cause of concren, just a question.
Over the weekend I decided to get a Sorority Tank and yes I am well prepaired if they decide to fight(I have a small 5 gallon tank to shove one in there if it gets too violent). So far within 24 hours no injuries just a little chacing if they get too close together.
So anyway my question is one of the Bettas, actually the biggest one(they all look about 9 weeks old) just floats at the top. She moves around the tank but always stays at the top of the tank. When I fed them this morning it looked like she ate a little but not much. Is this ok? Her floating there, is that a sign of something? All of the others seem to be ok, swimming around and exploring the tank...just not this one. I was considering putting her in a temporary tank alone.
What do you think?
