Are my BNs normal

[Fried]

Bought 2 females and 1 male adult common BNs. They all seem very shy and one of the girls likes to change colour and to lie on her back. I suppose this is all normal.

I have attached some pics of her and one of him just to show how handsome he is.

its normal, maybe add an airstone for more aeration. Male looks stunning as well. cheers and good luck jk :thumbup:

Thanks for the reply, I have 2 air driven filters in the tank would they supply enough air or are airstones a lot better?
