I am planning a large (at least a 48" long tank, maybe 72") seahorse display and would like to have at least 3 pairs for seahorses. I currently have a 92g reef and a 110 FOWLR, and I am pretty experienced in the hobby in general. I will be doing this from scratch, with all new stuff (my other tanks are pieced together...) and so I wanted to get advice on what the BEST equipment is for a dedicated seahorse tank. The smallest I would get is a 90 (48x18x25) gallon glass tank with a stand. For lighting I will most likely use LEDs of some variety or T5's. I assume I dont need a fuge as I want to grow macroalgae in the tank. It will have a sump with a good skimmer - what skimmer is recommended, anything special? Also, what is recommended for flow for seahorses? Would one or two MP10's be good, or are they bad with the seahorses getting caught in them? Would an oceans motions or other variable delivery return be better? Also, how big a chiller should I get for a 90 gallon? Basically I want to get the highest end stuff and make a solid and reliable system that other people can maintain if I am away.
As for the seahorses themselves, what do you recommend as the largest and nicest? I have seen some impressive pairs of orange brazilians....
Hey, I'm still a novice at keeping seahorses (not a novice aquarist though) although I'd say after reading up on everything about their care for 6 months (including rayjay's guide) I feel somewhat knowledgeable enough to add some input.
My set-up is only 30 gallons with mixed soft coral, SPS, and LPS. The guide for lighting a seahorse tank is to cater to the needs of the photosynthetic organisms first. If you plan on keeping corals, then choose the best lighting for them (LEDs, T-5s, halides). T-5s or even PC lighting is probably enough for macroalgae though. As long as the seahorses have some areas with shade, lighting isn't an issue for them.
1 MP10 combined with the return flow is probably enough. The oceans motions idea would be good too especially since there's no chance of them being caught in the powerhead. Seahorses can handle more flow than a lot of people seem to recommend. Just as long as there are areas of slack water movement too. The nice thing about pumps with variable setting is that you can turn them down for feeding.
Fuge is helpful since I've found my seahorses at least to be good hunters. Any live mysis or brine I've thrown in the tank are all gone by the next day. So the fuge will allow live foods to at least have a chance to reproduce and thrive. Plus, having another place for growing more macroalgae is very useful for nutrient export especially on a reverse time schedule or 24/7 lighting.
Skimmer is a must, that's where you should splurge as much as you can. Seahorses are very messy when it comes to feeding unless you can train them to eat from one spot every day.
Chiller for 90 gallon + sump: at least 1/5hp, preferably 1/3hp so that it's not running all the time in the summer.
There's no automatic feeder for frozen foods that's on the market right now, but that would be useful. You could make your own from this thread

H. ingens and H. kuda are the larger species. H. abdominalis is the largest.
Just my 2 cents.
