what seahorse to get??

[jeffscustomcage]

Am looking to purchase a seahorse and was wondering what is the easiest and best survival rate.
Thought i would ask the experts.
I have a 29 gallon tank
thank you

Erectus and reidi are probably two of the easiest but the erectus has benthic fry that are a bit better for rearing than the pelagic fry of the reidi.
