So I lowered the water level and a little too much the clown was touching the BTA as it had no choice and I guess the poor thing was being stung and started jumping about so I immediately increased the water level so he wouldn't forcefully be touching the BTA. After a little while I noticed he was touching the BTA and I guess had gotten used to the sting and wasn't jumping about like before so I lowered the water level again for as long as I felt comfortable with my torch and acro being out of the water. I have now let the poor clown go and returned the tank back to normal knowing full well it wouldn't host the BTA even though it was now comfortable around it.
In the future if I ever get another pair of clowns and a BTA for whatever reason, I'll make sure to tell my LFS I'd like this certain type of clown and BTA and to make sure they are hosting for at least a couple weeks prior to me picking them up. I have tried all the methods I have seen and read about and nothing has worked for me and I've stressed the poor little b******* out in the process.
