My tank is a 30 gallon tall
My bichir is about 5 or 6 inches but very skinny..
the tank mates are a catfish which i plan on taking out soon he's been causing issues, two rams, a non aggresive chiclid, a few barbs, 5 pencil tetras a sailfin molly and a swordtail.
i usually feed my rams and chiclid and bichir and catfish the sinking carnivore pellets they seem to eat those. other than that normal flakes. i have a nice tall cave and a log, fake plants but well planted, and i use just an aqua-glo for my light.
