No , gets cycled the same way, not worried about nutrients, I will have lots of macro algae that will pretty much take care of them along with skimmer. I tend to only run a skimmer, bare bottom and water changes. It’s always work great for me.
Been slow going, but it's there, I do want to add some color to it by adding some other macro, I do have some red in there , I hope it take off. may be a few small fish Not sure yet. my goal is for 2 pair of seahorses .
You can even have certain clown in the tank like ocellaris or percula . Banggai Cardinal fish can be be housed with them but as they mature you want to watch for aggression especially when they pair up and start laying , but then even that may still work. But if I was going to raise the seahorse fry I wouldn't they probable get eaten before I could get the babies out. That's why I never have anything but the seahorses in the past, I always siphon the little guys out and place in special tanks I made for them. I'm not planning on doing that and probably won't be doing H, Reidi , the babies don't hitch for first 14 days and you have to have them constantly be moving in a circular movement to prevent them from going to the top of the water surface and snick air, other breeds can hitch right away. I always work with the H. Reidi. you have to keep green water at all time and rotifers batches going, Lots of work, then baby enriched brine later on. Its a job, I was younger and fish where my life back then even more then corals.
