I recently switched my axolotls diet from frozen bloodworms to live blackworms. The first day I put in a large ball of blackworms into their feeding dish and they ate like pigs. I left for class and came back and noticed all the worms were gone. The next day I fed them again (they are still juvies) and they all ate but then I noticed that there were blackworms hiding in EVERYTHING. from the ornaments to under the food dish. I don't have an issue with them other than they infested my moss balls and are causing them to fall apart. Is this a common problem? I moved the moss to my shrimp tank to be cleaned but I would like to move them back.
