Scooter blennys are similar to mandarins as they are both picky eaters and mostly eat podlike food
It is a good idea to get a population of pods growing quickly. I got a scooter blenny and even with 2 feedings a day it wasn't enough for him. They really need to graze all day on them. Since I started growing some live phytoplankton there has been a HUGE surge in the number of pods in my tank so I would greatly suggest buying a culture. I have been adding 1/4 cup of isochrysis every other day in my 20g reef w/ 10g refugium and the only problem I have seen is a small jump in the amount of phosphates which could be because I didn't let the culture grow long enough to use up all of the available phosphates that are used as fertilizer for them.
mmm, never had a scooter blenny but I don't believe they need them to survive.. If you have a sump or refugium, I would just stick a ball of cheato from you lfs in there. Thats where I got all my pods from.. Also I had a wrasse until just recently so I'm sure he was munching on them, and yet I still saw plenty of them in my DT and sump
