right folks time for an update...
I changed the collection "trap" a few months back. Its now an ice cream tub with a filter foam along the front - its angled slightly so that as the water goes in - it flows out through the filter foam
this combined with the java moss its filled with are doing a great job of collecting eggs, and keeping them away from poop etc. Its working and have seen lots of tiny fry but I've not been checking it at all just lately (like last 6 weeks or so), Until last night when there was a rather odd coincidence of fate...
I scared our Congo tetras in the dark lastnight as i walked past the tank (they are wimps)... A lot of splashing like normal but something was odd - the splashing carried on once I'd left eh room to feed the other tanks. I went back in and all was quiet... but i could only find 9 Congos - we have 11 - well had 11.
I checked the trap (by removing it) and found a rather nasty dead congo in there
took the trap to the loo and it turns out that the splashing had been one of the adult males had jumped out of the water and landed in the fry trap. he was hiding under the sponge and decided to scare the poop out of me.
any way to cut this rather long story short(er) we have 2x 1/2" syno petricolas in the trap
However - I have a horrible feeling that this is all that was left after the first congo got trapped.... there are about a dozen small fry so it doesn't make sense that only 2 have grown up...
So the bad news is that we lost a Congo (and probably some fry) but the good news is that the new trap is working and we have big fry
I'll get some photos tonight - I'm going to move them to the zebra tank tonight - to keep the fry in that trap company
