Hey guys I just got a new Lima baby hes only about 5" long, hes been staying towards the top by my heaters tho for some reason is it because its a new surrounding? What should he/ she eat? I have sinking shrimp pellets, floating Hikari gold, sinking omega pellets, some carnivore sinking pellets, frozen blood worms, frozen brine shrimp, is that okay for it? And how long it it take for it to grow to its full length, dont they grow to about 2'?
