I'm really interested in keeping seahorses and pipefish, what species would you recomend for say, a 20 to 30 gallon. I know they like plants and things to cling on to. What species should i get that is really hardy? Shouldn't the water be kept at around 75 or so? Myisis and brine are what I hear of most often as far as eating goes. I understand different species have different needs, and some suggestions and a description would be great.
