Im my opinion for clean up crew, I'll go with Scarelete crabs, emerld crabs, blue legs crabs, peppermint and skunk scarelete cleaner shrimp, astrea snails, and a fighting conch.
Scarelete crabs scavenge left overs and eats aglaes.
Emerald Crabs eat bubble and hairy algaes, including scavenge.
blue legs crabs scavenge and eat algaes.
peppermint eats aptasia and prevent out break of it, including scavange.
Skunk Cleaner scavange left over and clean fish from parasites.
Astrea clean windows and back wall, including rocks from aglaes.
LAST Fighting conch are best for sand shifting and clean out your sand bed from algae built up on sandbeds. The suck and shift the sand so the sand doesn't have a dead spot for bult up.
