Dont know what is happening, but i have hundreds of small fry in my fuge, swimming in and out my cheato. Would love to know what they are and how they got there. If they were in the main system they would have to get through a skimmer and then a pump into the remote fuge. I noticed them about 2 weeks ago so they have found food on their own, now the only fish spawning in the system are the green chromis and the clowns. Wonder if i picked up fish eggs during a water change, we will soon find out i have started feeding them yesterday and they are about 2mm in length at the moment, sorry cant take pics as they are too small.
