Anybody Keeping a Temperate Tank?

[Beverly]

Am considering setting up a 90 gal temperate tank to house captive bred pot bellied seahorses (H. abdominalis). One thing for sure is that we will need a chiller if we actually decide to set up this tank

Would like to know if anyone keeps a temperate tank and what kinds of snails, shrimp, macroalgae can withstand temps of 67-69 F? Will Fiji or other tropical LR be suitable for such a tank?

TIA.
