I've got a 29G BioCube that's filled with corals, a clownfish and a dwarf angel. I want to move all of it but the clownfish into a 75G tank and take the gbta's and rbta from that tank (with the much bigger clownfish that hosts the green ones) and move them into the nano. Don't know if it's possible to introduce another clown and the nems to the little clown left in the nano without ending up with a dead fish, and I'm wondering if anyone here has done the same and if so could you share your experience. At least it won't be hard to get one of them out of there if it ends up being ugly.
How long has the one been alone in the nano? Clowns kept alone turn to female, and once they become female they cannot go back. The larger one certainly has made the switch. Its risky - especially depending on the species. If they're maroons, one will almost certainly die. What type of clowns?
Another option is to get them to pair in the larger tank then move them both.
