I just bought a sunburst seahorse and have never cared for a seahorse before. I have been feeding him grass shrimp that are gut feed cyclopeeze and flakes. I have read it is better to feed frozen mysids in a feeding area so I will make one but I am curious about the fish in my tank. I have a 20 gallon with 3 blue/green chromis a six line wrasse and the sea horse. they all seem to get along so far it is day two. Anything I should watch out for?
