this is the bigger one which is still eating mysis and pellets, and graze around all day
this is the smaller guy which i dont think i have seen it take prepare food just graze all day but i am pretty sure he was eating at LFS.
they are in a 22 gallon tank
with 4 PVC pipe 2 on each side, and a dead rock on top of one the pipe lay againt back of the glass to create another hiding spot.
the big one will chase aggressivly when the small guy go to the other side, sometime big one will even chase it when the small guy is no where near him.
maybe i have bought a pair that the LFS just put together? if thats the case purchasing 2 indiviudally is $40 cheaper than buying a pair....
