I'm currently raising my third batch of kribs( about 30 in this batch), they are with their parents as i have always done,,,,,,,. when they breed i usually see at least 250 eggs on the rock inside the cave, and only end up with 20 or 30 fry( no gravel vac.- ing),,,,,,,would i have more success if i removed the rock with the eggs attached and placed it in a separate fry raising tank?,,,,what are the risks?,,and what is the best procedure to use to accomplish this?,,,,thx all !!
