I've had a look, and gulpers would be a bit big at 12in. But they are a very cool looking cat. I'll keep them in mind for future tanks. The banjos and raphaels are a must have I reckon. So I reckon 4-5 pictus, the 6 cories I already have, a banjo, a raphael, a BN (That I already have) and a school of tetras should be great. But if you reckon I should have a look at any others, just let me know. Cheers, Jim
