Hehe, i have one of those too! They are hiders too but with a bare bottom tank, you can look under and see everything. Mine hides all day and explores all night.
Once you start getting into Synodontis's it starts getting price, except for the featherfin. If your looking for cool looking small catfish then synodontis are the was to go.
Hmm Synodontis Angelica (Forget the last part of scientific name LOL) I love these Syno's because of the polka dots and the lyre-tail altough they are getting pricey in the trade as they are not allowed to be exported from their country of origin altough there was one at one of my not so lfs and it was £24 (45 Dollars?) which I think is a fairly resonable price.They grow to 20 cm and thats all that I know about them really...Maybe a giraffe catfish..
