Would a midas blenny work in a 20 gallon long? Ive seen mixed reviews on this. Some say its ok, others say not ok but the ones that so not ok say so for a regular 20 gallon, not a 20 long. they need a 30 gallon on LiveAqiaria, and a 20 long has the same footprint as a 29/30 gallon. plus they perch a lot, so length would matter more right? So i think it'll be ok in a 20 gallon long. what about you guys? what do you think?
