Hi. I followed a link to here from Monsterfishkeepers.com and thought I'd check it out. I presently have a 75 gallon tank housing 13 congo tetras and 2 female kribensis. My filtration is an Aquatop CF MKII Series canister filter with a large pre-filter sponge and containing 141 API BioChem Stars. I am running a bare bottom but have lots of faux plants as well as lots of hidey holes for the kribs.
