newbie

:nfs: .. this isn't really on topic exactly - but as a newbie, I'm hoping you won't mind I've recently introduced dwarf gourami's to my tank - first I got 2 flame red and then just this weekend 2 blue - they're just lovely and seem to be fitting in with my clown loaches and my bottle nose very amicably = so if anyone would be so kind as to please give me any hints and tips on how to keep it that way - I'd really appreciate it -I have absolutely NO idea what sex any of them are!! but they all seem to get on really well. The last thing I want to do is build a big hole for myself :digH: - thanks everyone
