I have a question hopefully you guys can help me. This time around my the eggs hatched and the parents have been able to take care of the wigglers up until free swimming stage. What I'm noticing though is the wigglers swimming everywhere around the tank. Some of the are still on the cone and others on the side of the glass near surface. is this normal? should the wigglers find their parents right away? Whats the right lighting to keep on the tank(brightness)?
