Dd1 has been keeping on to get some fish so i have told her that she can have a tank for christmas (just a small one), we have been to look at fish today to see what she likes (i know its a long wait until x-mas). All i have ever had is goldfish but we would really like to try something tropical/warm water, i showed dd1 the guppies and tetra's and she seemed to like them, dd2 has got her heart set on a clown fish (nemo), are guppies the easiest fish to look after? are clown fish a bit tricky? (wouldn't want one if i was likely to kill it as they are so pretty), can anyone reccomend any other fish for a small tank?
