Seahorse tank size for breeding - Any experts?

[Does anyone know how high of a tank should be used for a pair of mating seahorses? I've have heard 20" is enough, but I have also read that it needs to be at least 30" high. These would be the lined seahorse (Hippocampus erectus). Thanks!]
 
the larger ones can get up to 7 and 8 inches, not very often but some times even bigger
