Haha funny you say that David. The two you said to leave out are the two that I had been offered for free from my dad lol he said he has jeaps of jds in his tanks and hadnt had any issues but then he did have a few fish in each tank, the Plecostomus is very large (otherwise I wouldn't have considered him at all... too common lol) yea the height is tall not to mention it's a meter off the ground! (10 mm glass) But hubby wanted that height so he can struggle with the cleaning and arranging of everything. We will be using mostly sand and driftwood I think. I think the peacock eels would be better suited over other eels as far as aggression goes too (thoughts) And definitely agree on 2 smaller bichrs. I just don't want to fall into having a boring tank
