Just a quick update, found about 4 dead, can only see about 5, searched invain with bright light behind but unsure as to where the other 15 and now newly hatched eggs have gone lol! (All eggs on plants now disappeared)
Also little good news, found 4 eggs in pygmy cory tank and two fry, have put these in a net in front of filter output (little like Harlequins setup), was going to transfer two fry over but thinking double chances two different places. I know that you tell cories apart from above (still havent leartn this yet) but one does look pregnant still. They are defiantely keeping me busy!
