My seahorse tank is finally complete and now I am starting a 30

If you are that offended by his post then perhaps this isn't the forum for you.
It was an honest post elicited by the facts stated in your original post.
IMO, you need to start to trust more knowledgeable people regarding seahorse keeping as just knowing salt water aquariums is far from sufficient.
Even keeping H. fuscus would be challenging long term in a tank that small, but H. reidi, H. erectus, or H. kuda and other standard sized seahorses would require very due diligence to housekeeping, and, frequent large water changes, to ensure long term survival.

Viperfish, a 14g is actually not good for dwarf seahorses. (unless you have about 150 or so dwarfs in it)
Better to use a 5g because dwarf seahorses usually don't hunt for their food but rather stay hitched and wait for their food to come by so they can snick it up, requiring heavy food density, a big waste in larger tanks. (uneaten bbs need to be removed before adding the new enriched bbs)
Sengerseahorse will have a chore to keep his dwarfs fed properly in the long term.
