Sounds like an alternative to ImmacI have so many that I adore, but would have to say my best is Jethro the common plec as he is so friendly and gives me kisses. (ok so he sucks my fingers, hand and arm but I call it kisses lol)
as a matter of fact the have had far too many little catfishes.
I suspect the blue rams I hope to be getting soon will be hot on their tails for the title of favorite fish.
