Thank you everyone for all your help and encouragement.
I don't think I can raise a 150g aquarium until I settle down permanently somewhere. I'm going to give away the fish that won't fit in the 30 gallon tank and just keep the angel fish and gourami. I was really hoping to keep one Parrot, I like how they look but they'll outgrow this 30g tank in no time.
Giving the fish to people on the MFK forum is a great idea. If any of you guys or gals PERSONALLY know of a really good owner in the NYC area who's willing to pick them up, please pass the word on. I want to move them as soon as possible before my dad gets back. That's 3 parrots, 1 healthy arow, 1 sick arow and 1 oscar. I'll make a post in the right forum soon along with better photos. It's extremely important to me to know that they'll go to someone who actually knows what they're doing and has the adequate knowledge and equipment/environment to house these fish. These fish deserve a good home after what they've been through. I'll just have to weather the **** storm when my dad gets back, the fish will be happier at least.
I doubt anyone wants to pick up a sick Arow so I'm going to try my best to nurse it back to health for now. Thank you so much Lupin for the detailed instructions on treating my Arow, that was tremendously helpful. I'm going to hit up the pet store tomorrow morning for the meds listed and let you know how the treatment goes. I can't stand watching an animal scratch at an itch until the skin comes off, that's probably one of the worse tortures I can think of.
I've got a LOT of learning to do so I will hit up this forum often with a lot of asinine questions. Please bear with me. You guys have no idea how much I appreciate your generosity, I really wasn't expecting this when I came here.
