Can you get jelly fish in the u.s. and if you can what is the care level abs ate there easy jellies to care for thanksSurgeon fish or tangs won't work at all in a 29 gallon even a yellow tang requires a larger tank, I'd stick to smaller wrasse species clowns cardinals firefish. Sea horses should be species only. Tangs are too aggressive of eaters to mix with sea horses but regardless your tank is too small for both unless you get dwarf seahorses, which are difficult to care for
