If lets say I have a 125G tank filtered by 4 AC110s and 2 Fluval 404s, and I must keep some fish in it that are known to be escape artists (eels), how would I go about covering "every hole"? I am not sure if smply putting up some ductape would work: Even if I managed to assemble pieces wide enough to go over the powerfilter's outputs, wouldn't tape eventually get wet and come apart? On the same note, water saturating the adhessive side may eventually drip into the tank. If so, how would it affect the fish?
