Wilburrrrrrrrr? Why don't you feed me? Thats a original Mister Ed Seahorse. They do not do well in anything but larger tanks. They are kinda hard to wean off natural diet of Alfalfa and wheat. They do produce a lot of waste. You may need a green Apple dispenser with extra Carbon to remove excess(censored) ? I think Deltec makes a special grade dispenser but they are expensive...
I hope this helps
Well, the usual rule of thumb is about 1 hand per 20 gallons. However, as with most "rules of thumb", this is highly dependant on the particular feeding needs of the species and other bioload in the tank.
I would reccomend going at least 50 gallons per hand in this case, but keep and eye out for signs of starvation.
