My Cons bread recently and its a first for me. they are in a 150Gtank with about a dozen other cons. the yolk sacks are now gone and I was trying to feed them brine shrimp today but to little avail. as soon as the shrimp hit the water the other cons snapped it up. I have a 20G tank to move them to and I heard syphoning is the best way. tried it but I couldnt get any of them. any help is appreciated
