My mums winter koi tank had a very poor sump, we lost a weather loach that we rescued and assumed it was in there, after about 10 minutes of stomach turning feel a bouts we just assumed it had jumped the tank and managed to reach the drain... We got an external filter a month after and ceased use of the sump which was left under the tank for about three months (procrastination's a b****) we were running out of tanks so decided that the old three part sump would make a good tank, mid cleaning of a three months stagnant brown faeces filled freezing cold (it's Scotland mid winter so were talking -0 c
) gloop we see something writhing about in the filth... Long behold the loach, severely emaciated a d oxygen deprived, yet barely alive! We immediately shifted him back into the tank. A few days later and he was back to himself and plumping back up. The external filter isn't set up to move the surface properley so we have a grated fluval powerhead doing that, anyways he had basically managed to get stuck in it, then struggled and made it halfway through, so his tail was hanging out the bottom and his shredded and mangled face was peeking out the eyelet, needless to say we were pretty hacked off -.-
