Quick CUC question
Been away from the forum but hopefully I can be back!
I have a 125g tank that's been up for awhile and I need some help finalizing my CUC. Currently I have 1 cleaner shrimp, 2 emerald crabs, 4 red leg hermits, and only 2 or 3 astrea. I know I need some more, especially in the snail department, but I cant find a good number of what and how many. Any advice would be great. I definitely want to get another cleaner shrimp, as their personality is really cool. Generally do people count cleaner shrimp as part of the CUC? Or is that mainly relegated for the snails/hermits?
Bonus question. I have a 40g sump with a refugium. I was wondering how much chaeto i should start off with. my small amount definitely hasn't taken off. I also read somewhere that its very beneficial to keep a sea cucumber in the refugium...is this true? If so...why?
