I was wondering; suppose he's within acceptable limits when it comes to toxic NH3-NO3 and NO2 levels, not sure he's checking up on pH and stuff, do you consider a 55 as an (over)crowded tank? I mean 4 cichlids measuring 4/5 inches and a 4/5 inch pleco on the bottom...they still have approx. 11 g each. I know some will grow like 10 inch or even larger but, for now, I wouldn't call it an "over-crowded" tank. I guess with adequate filtration it should be okay ?? Or am I completely wrong about this.
