I came home from work today to find 7 dead fry on the bottom of my tank. I thought i better take the fry from the cave just incase he starts kicking them out. I ended up with 33 fry plus the 7 dead so a spawn of 40 which is pretty good. The difference in size between the 33 and the 7 was huge. The surviving ones had bugger all egg sack left where the 7 still had big egg sacks with no colour to their body. So im wondering if he knew they were no good and kicked them out. Can anyway tell if they do that?
