Well, here's my setup for dwarf seahorses (no seahorses currently but soon will be ordered)...
Tank: 2.5 gallon tank (mini bow)
Filtration: DIY sponge filter (works much better than the Whisper that was in there before)
Heater: Tetra 2-10.
Light: ZooMed Reef Sun 10-watt mini CFL (screw in).
Substrate: Arag-Alive sand
Decor: Florida dry rock, fake grass plant, scallop shell, collected and cleaned barnacles, caulerpa.
