I have a 6' long sump (about 100 gals) in my basement. It only has a Skimmer, heater, and a bunch of live rock. I also house a mated pair of clowns in there. I plan on putting the rocks in two piles, adding a DSB, and plant a large turtle grass bed in there.
My concern is for the clown pair.
Help me pick the best option:
1) Move the clowns to a small tank until the sand storm subsides (catching 2 clowns in a 6' tank will be difficult).
or
2) Add the sand while the clowns are still in there (I'll have an extra mechanical filter going to clear it up faster).
Which one would be less traumatic to the fish?
