yeah they will be underneath driftwood and sand so thats not a problem and yeah i plan to vaccum them when i do waterchanges so that should help and thanks i actually thought they grew slower than that so thats great to hear once they reach the 5-6 mark they should be out the of the woods with danger from the baby cichlids, soooooo will be getting the knife as soon as i get my tank set up in two weeks!!
