Sorry NoahsMommy, I was going to get my dad to come in and answer your other questions, but he had already gone to sleep (he has a night job). He would LOVE to answer them tomorrow though, fish is like almost his life lol. So whatever 411 you get tonight, I'm sure my dad can add on a few tid-bits tomorrow. As for me, I think I know what to do about the sucker fish, but I don't want to give out false information (IF it's false, I'm not really sure...). Good luck with the tank!

P.S. My dad said he thought those 'Bali' Sharks are actually 'Bala' (I didn't ask him how to spell it but it sounds like bell-a). He didn't post it though, he wasn't sure if that was true or not. Can you confirm?
