No luck in selling this guy, not anyone interested at all. Found an affordable 90g tank to house him for awhile. Looks like sand is the recommneded substrat, but what about decor? Sticky says for more of a bare tank. Thought these guys needed places to explore and hide? Also he has not touched the guppies in the tank, would a school of giant danios work in the 90g? They are cheap so if a couple get picked off it's no big deal. Also anyone keep plecos with fahaka?
