Drawf seahorse in sump?

[walkietalkie25]

Approximately 4 months ago I wrote on this forum about keeping a dwarf seahorse in a sump. I had never had them before, and have a big reef tank. I ordered a couple before researching how to care for them! (Impulse buy, dumb, I know.)
All of you guys that are experts in this field said they could not survive, even though my sump is full of mysis shrimp, because of the water flow, and the 80 degree temperature, etc.
Just thought you might like to know that one of them after all of these months is alive, healthy, grown quite a bit, and enjoying his fill I of mysis shrimp, I guess!
