I am moving house soon and taking this as an opportunity to rethink my tanks :) as I will have to clear everything out of them in order to move them anyway!
I have four tanks, one or two will be used for rearing BN catfish (ancistrus) fry and housing their parents and a few random fish which I have left from 'old' groups and don't want to expand these groups again (2 gold WCMM, one balloon molly, two guppies, one clown killifish, one badis badis and a female betta).One small one will go in the kitchen and probably house my frogs, so this leaves me with the largest, a 29 US gal. All I will have for this tank at the moment is a large ruby shark - I have had him since he was really quite small so don't really want to re-home him, although I know he could pose a problem living with other fish.
So - I just want a small number of larger fish which can live with a ruby shark with no problems. I like interesting and unusual fish such as ghost knife, and those small eel like fish (stripey black and orange) whose name escapes me at the moment!
