Fish Crazy
I would like to start a pleco tank in my new 40USgal tank. Would a clown pleco and a rubbernose pleco work? And could I fit anymore in it?
Those 2 would be fine together, neither being aggresive and don't grow too big ( both get to around 4" )
Plecs are naturally territorial and will need their own space, don't be surprised to see a bit of squabbling at first but they will get on in time.
As for adding other Plecs I think it can be done in a 40g. I'd keep with the smaller ones, under 6" or so, just do your research and you should be fine. Plenty of rocks and caves and a piece of wood or 2 along with good filtration should keep them happy.
Planetcatfish.com has a list of all Plecs known and tells of their needs.
I've just got an L260 Queen Arabesque and think it's a great looking fish, a great fish that I'm sure you'd like.
HTH.
I think Rubbernose/Bulldog plecs (Chaetostoma species) need cooler water with a higher current than Clown Plecs.
