and they immediately paired up. I was expecting some difficulty because my other clown had been in the tank for about a year and never had another clown in the tank with him ..er.. her. Went to the LFS and they had 4 in one tank got one that wasn't the biggest in that tank and took him home. When I let him go in my main tank yesterday they immediate went to each other and haven't left each others side since. It was pretty cool.
