Man. Gotta love it. LOL. This thread inspired me. As seen above in my post, my clowns wouldn't leave their corner long enough to hind the BTA I got for them. They were paried up themselves (obviously happy) in an absolutely empty corner.
After reading this thread, I re-scaped my rock, and moved the BTA to the empty corner that the clowns were hosting. It took two tries and three days, but, finally one clown went into the BTA last night in the corner that both clowns were hosting. So, at this point, all three have at least been in the same corner for three days, and one clown (female) has started hosting the BTA. I figure the male will follow suit, and give them some time to sort it out. They were all in the far corner of the tank where they can't be seen, but, at least they were together.
Well, I wake up this morning and the BTA and female clown have both moved to the middle of the tank, and the remaining clown is still in the empty corner alone. LOL!!!
Well, I guess only time will tell if all three live in together. For now, I'm just gonna sit back and watch how this plays out. LOL...
