A quick follow up for anyone interested:
The three all came through TTM without issues. I used 2 ten gallon tanks each with a heater, power head and PVC hiding spots. No filtration. I dosed prime on day two of each transfer. I fed very frequently, but small amounts and I removed uneaten food and waste with a baster frequently.
The fish seemed happy and stress free in the 10 gallon tanks. They would meet me at the glass whenever I came near. The only exception was the yellowfin would be stressed for an hour or two after each transfer, but that seems pretty typical for them.
Cant wait until they hit DT!
Thanks RC for all the guidance and advice!
