Based on the fact your have 34 Exo's (which by the way must look great) I wouldn't suggest it. its a bit risky.
I had 9 Exo's, one night I had to move two FW cuda's into their tank. The Cudas were about 4"-5" the exo's only about 1"-2" at the time. The next morning both the Cuda's completly stripped of all scales and dead.
I am after an ATF myself, Where are you getting it from. Cheers
