Hi all, i am new to the forum! For my birthday my mum and dad bought me a tropical fish tank. It has been set up for just over a week. Today, i went to my local fish centre, i got the water tested and it was fine to keep fish in !!! I looked around at the fish and decided that i would go for the easier type of fish (because there is a bigger variaty). I bought 2 glass cat fish to start of with. I put them in the tank (after balancing them on top, then adding water etc). They have been in for and hour now and dont seem to be doing anything They are sitting behind the biggest ornamant and there back tails are moving like mad. The temperature is 26 so far ... whats wrong with them ???
