I learned about multies the other day and I think they're probably some of the neatest little fish ever. Unfortunately to be comfortable they would need around 30 gal spcies only tank. someday, maybe
I've always been a big fan of puffers but again the need for a whole new tank of significant size would be required. except for dps which I may be getting sometime.
Arowana, discus, any of the Polypterus, giant (mbu) puffer, congo puffer, a big reef tank, black ghost knife, baby whale, etc. So many fish, so little time/space/money.
Im going to get discus/cardinal tetra/clown loach.
Though if its anyhting i want it would have to b most saltwater fish. Though im young and i cant afford all the saltwater stuff and im not willing to keep up with all its maintience
ive always wanted sea horses!! thats sw..
for fw i would love a black knife, or sting ray, hey actually something as simple as a school of 50 neon tetras, but I'm not paying the prices for those little guys lol
