Never keep dwarves in a sump of a reef tank. The various factors are:
1.) Flow- Seahorses need extremely low flow, dwarves need an even lower flow. A single airstone in a 5 gallon aquarium is all the flow they need, if more they get blown away.
2.) Temperature- Your tank is much too high in temperature than what dwarves need. Anything above 74 degrees is too high for tropical seahorses as it makes them prone to a million health problems.
3.) Amphipods- Amphipods will kill adult dwarf seahorses.
4.) Food- Even a couple dwarf seahorses will kill a copepod population in a sump, you'll need to hatch live brine shrimp daily.
5.) Hydroids- Unless the live rock is treated with panacur (which will kill all corals and most inverts) the hydroids will kill the seahorses.
You can add the seahorses to the sumpbut they'll just die in a few days.
For the sake of the horses dont put them in.
