i inherited a pair of Kelloggii?( i was told by their previous owner, my neighbor's kid who went away to college and her parents knew i keep reef tanks so i was their choice of beneficiary.) don't know male or female(yes i did some research but still can't tell about the pouch), both about the same size 5-6 inch. both yellow, one is paler than the other. they share the tank with three small (2-3 inch) wartskin frogfish (Antennarius maculatus), one turbo snail, one trochus snail, a couple of small hermit crabs, a mated pair of coral banded shrimps and live rock with some xenia, halimeda plant, and mushroom on it, in a tall 15 gal. with fluval 405, redsea prism pro protein skimmer, three small power heads, one hook up to a spraybar to help clear the bare bottom. plus a micro chiller that's not hook up since the temp is always at 78 degree. the seahorses are fed twice a day with frozen mysis and once with brine shrimp ( i heard of "enriched" bs...how do you do that?) just to give them some excercise and my kids love to watch them chase the bs. the frogfish are hand fed frozen silverside once or twice a week and once a month a live minnow. i have the set up for over a year and a half now and everything seem to be doing well. any suggestions or comments would be greatly appreciated. i'm not a big seahorse guy but i've grown the love them. the kids always bring home friends to check out my tanks and the seahorse tank is definitely their favorite.
