I just bought some spirulina algae food for my violet goby and he appears to like it, i guess maybe because they really smell compared to the normal tropical flakes i was attempting to feed him. Does anyone know whether it would be ok to keep my dragon with a pleco or algae eater or just a bottom feeder in general because i want a fish that will help clean the tank. I thought the dragon goby would do that but he just eats food thats near him.
