I will be moving my ornate and guinea bichirs out of my 75 in a few weeks and with 2 sens, a delhezi and a bowfin there isnt much movement. I want some small fish that wont get big but are big enough to not be eatin. The 3 bichirs and bowfin which will be left dont really swim much so the tank looks empty a lot of the time. This is a hard question because i want schooling fish that are small so that they dont crowed the tank but they need to be big enough not to be eatin by the bowfin and 3 bichirs. Any ideas are welcome. Thanks in advance for any advice. Btw the 2 sens are about 8'', delhezi is 6'', and bowfin is 4''.
