Hi Neon Dotty! I recieved your PM regarding my seahorse set up, and I was having difficulty responding so I thought I would just make a post. "Pecos" (my orange brazilian seahorse) is kept in a 16gal bowfront ($150 including stand and hood from Petco), with a small HOB
filter, a ton of prolifera (broad leaf macro algae, not sure if i spelled that right), some LR
, and some live sand. The only other inhabitants are a few snails, and a green brittle star. Because he only eats live food (small ghost shrimp, and live brine shrimp) the water quality is easy to maintain, with the occasional water change. Thats all there is to it! Hope I could help give you some insight.
