The second try is over. Lost the remaining two cheeks - one 2 months ago, the other a month ago. Not sure why.
I could blame the 15 small ATF they were with but having had my two big ones preyed on by VATF in a 4500 gal, I was watching these little cheeks like a hawk for any exterior damage. None happened except for them bashing their snouts every now and then due to their great skittishness (which I also didn't quite understand).
The second cheek might have died from self-committed overeating. It ate a LOT of pellets that day and it's tummy is chock full even in the post-mortum photo (the tail was bitten post mortum):
The exterior damage on the last cheek is post-mortum from what I could tell (there was nothing on it while it was alive) except for the eye damage. That must have happened a while ago:
I wonder if the ATF were stressing them out (or some other tank mate) some how other then biting or bullying. The cheeks were 6"-8" while ATF were 3"-4".
Anyhow, my miserable yellowcheek record as of today is zero for eight. If there is ever another try, I should aim to keep them separate or with the meekest of tank mates.
