Ive been talking to a few members about my issues with my two common plecs, first just want to say thanks to them for a nice welcome and good advice! i was told 5 to 6 foot is ideal for two plecs...ive so far had no luck at all ive not even seen one for sale at all...how long would a 4"foot tank hold them nicely for? As theres a few knocking around and tips on were to look for tanks, id get a 6 foot one if i could fine one thanks again x
