it depends on your other fish and coral species. pipefish will only survive in a tank with peaceful fish and nonaggressive corals. you should also have a supply of live brine to feed the pipefish just in case it doesnt take frozen.
It eats Hikari mysis, prawn roe and cyclopeeze with vigor but its taken some time. The roe was the first food it took and I'd recommend starting with that and having all three on hand from the get go. This is a yellow multi-band which are often the most challenging to feed ime. This one is doing pretty great.
