Lined Seahorse, Hippocampus erectus. These sell by such names as “lined seahorse” and “black giant seahorse”. They can reach a total length of about 8 inches, but the ones we sell start at 2.5 inches length. They can be male or females but we will sell them as we have them available
These are wild caught lined seahorse and although they have been kept in a medicated system for about two weeks, it’s always a good idea for you to quarantine them for another two weeks prior to adding them to an established system. Seahorses require live foods such as enriched live adult brine shrimp, live mysis shrimp, live feeder guppies, or any other small live fish or shrimp. We haven’t had any trouble getting our wild caught seahorses to start eating frozen mysis shrimp and often that are already eating the frozen shrimp before they leave our warehouse. If you have trouble getting them to eat the frozen mysis shrimp, try feeding them enriched live adult brine shrimp for a few days and then try weaning them off the live food and onto the frozen food. They will not thrive on just live brine shrimp and will eventually waste away unless you are enriching the shrimp right before you feed them to the horses.
Seahorses are reef safe to a point. They generally will not bother other fish or invertebrates, but may go after very small fish or small shrimp. They are not aggressive feeders, so they require extra care in a tank that has active fish (most people would not recommend mixing them with fish because they are such passive feeders.) Seahorses should not be put in tanks that have sea anemones, corals, or zoanthids because they can sting the horses and the anemones may even eat them. Mushroom and leather “corals” are OK, as are gorgonians.
Seahorses are not for the beginners because of their picky feeding requirements, so this shouldn’t be your first fish.
