Got an early Christmas present last night when I was rinsing a Eheim Ecco external filter. When I opened it, there was a large fry sitting on top of the basket! I removed the basket and drained the cannister and found five more of various sizes.
I use Ecco filters in several cory tanks, but I have an algarde 200 filter sponge over the inlet to stop eggs or fry getting sucked out, but there is a gap around the top of the strainer, so even with the sponge in place there is a tiny gap left for fry to get thru. I have no dea how many were lost this way, but at least now I know why the Gossei fry were not surviving very long.
