I have a Wyoming clownfish and a spotted mandarin goby I feed them one shrimp cube a day they are getting bigger tho does anything think I should start feeding them 1 and a half or 2?
I would suggest mixing up your feeding with a frozen mix such as Rods or LRS to supplement with the mysis shrimp your feeding. Feeding as much as they can eat in a couple minutes is plenty.
How long have you had the Mandarin? Does your tank have a sustainable copepod population?
