Hey everyone, new here, just a quick question about my new betta fissh, I got him on saturday for pets at home. I have him in my 23l fluval edge aalong with some danios, he gets on fine with them, they just keep out of his way. I've noticed that a lot of the time he will swim at the back of the tank under the flowing water from the filter then under the filter intube then turns around and goes back again, he does this no stop for a while then gets back to just swimming about. Just wondering if this is normal?
Thanks
