YIPPEE! Always nice to help stock a large tank, cuz noone can flame on ya. Well, do u REALLY like the masked puffer? Becuz, Goldens are cool (but expensive) and Porcupines are VERY cool, the coolest of em all I believe. On the better side though, USHER himself, the KING of POP has a masked puffer. Still, porks are SOOO cool, and I think ud like one. An eel? U looking for sumthing aggressive or passive or wat? Also, definitely go with a Volitan Lion or sumthing of the sort. He would THRIVE in yer tank. Do u like rays or sharks? Those are good options for you. Like, if u set up yer rocks on either side of the tank, with plenty of swimming room in the middle, you can have sharks and rays no prob. Clown trigger sounds good BUT, that would mean you couldnt get an eel. You know wat eels are cool? Tesseletta eels. Snowflakes are allright, but they are pretty common. So, im thinking lionfish, puffer, eel, trigger, maybe a ray and a shark. Shark would be like a leopard shark or a bamboo shark. Ray could be a blue dot ray. Also, maybe a nice big tang, like a vlamingui tang or naso tang. Okay, have fun, and ask questions. OOO, one more, HARLEQUIN TUSK. Those are darn cool fish, and they would like yer tank, as long as you get it big enough. Do a search on em, ud like one.
