Does anyone have a rough idea how long fry should be kept in a breeder net? I first saw these tiny little tadpole like things while doing a gravel vac about 3 weeks ago. Then I didn't see them again until last weekend and they have the shape of baby fish but still quite tiny. I managed to net 3 of them and currently have them in a breeder net. I know they will get eaten cause as soon as they poke out of the gravel the fish head straight for them. How big should they be before I let them free. I assumed they were platy babies but know I'm not so sure. Anyways other tankmates are platys, balloon mollys, white clouds, danios, pepper corys, blue rams, otos, betta, gold nugget pleco and ID sharks.Tank is 55g with quite a few plants, driftwood and rocks. Thanks in advance.
