Plan for 20 gallon tank

[elkman]

Tank plan

2 scarlet hermits

10ish snails

1 conch

1-2 Pom Pom crabs

1 porcelain crab

1 spider decorator crab

1 fire shrimp

1 pistol shrimp

2 clown fish

1 Banggai cardinalfish/royal gramma

1 yellow watchman goby

Will this work? Are there any adjustments I can make?

I would scratch the decorator crab and the hermits, If your having any soft corals. They will both become problems IMM. The dec will pick them up, the hermits eat whatever.

Snail count is good, make sure a few are sand churners like Nassarius.

Rest seems ok to me.
