So my brother just finished the setup of a new 210 g tank with a 55 g sump and last night we transferred the fish into it. Woke up this morning hearing the pump going weirdly and discovered our beloved 9-ish" fire eel dead inside one of the pipes leading to the sump. Both overflows were covered by plastic grated caps and some filter media. So how did she get sucked into it? The only openings of the filtration system in the tank are the two overflows and the return. Only options are the overflows but they were covered, can't even fit a finger through the holes and even those covers were covered with porous filter material. UGH! D':
