Take the fry out m8, if they are still small enough get them with a siphon, into a bucket with tank water. And stick em in a 20 (bigger the faster they grow). I find that when my L.ornatipinnis spawn in my 55 they used to grow faster in there vs in a 29 grow out tank. But once i started changing the water 25% every other day + 3-5 feeding daily of BBS + ground (or powdered depending on size) NLS grow formula they have started to take off! People also say that decapsulated brine shrimp eggs are great grow out food.
I never trust my pulcher with their fry, every single spawn to date has been eaten by them, always notice the spawn too late.
If the make it to 1" I would love to trade/buy with/from you; assuming they are not pulcher :P
