I meant what size are they, I am no tank expert either. My fish I buy from a couple of lfs that are very good, Maidenhead aquatics and the waterzoo, there are a couple more round here but they are not as good IMO.
Hi, I'm not sure of the specifications of your tank, but it doesn't sound all that big and you sound like you have a few fish - are they all recently added - how long has it been set up?
It may well be worth you reading: http/www.fishforums.net/index.php?showforum=26 as otherwise you could lose all or some of your fish. Apologies if you know this already but it is better safe than sorry.
