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!:D
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? :)
