Thanks for your question! I almost went into the details further because I'm really excited about it, but thought maybe others wouldn't be so much. Anyway, here's what I'm planning for now - and those with experience feel free to offer suggestions:
The 220 is coming with 2 oscars and 3 large silver torpedo fish that the seller called pencil sharks, although, i looked those up and they do not look at all like what the internet is showing me - so I need to properly identify them (will add pictures to this thread soon, but at work computer atm). Also a couple of plecos. This is going to be just a display tank in my living room. My boyfriend and I are kind of on the fence about whether we will keep the current fish it has or try to trade or rehome them. I love the idea of owning oscars, and other big fish that I've never been able to keep before - but I also really want to do a beautiful planted tank and I can't really do that with these fish I don't believe.
Most of the other fish tanks had only a few fish in them (like a breeding pair and pleco, etc.), so though they are coming with fish, it will be easy to redistribute them to community tanks if desired, or can continue with breeding attempts.
One of the 75 gallons we are actually giving to a guy friend who is going to spend an entire day helping us move and set up all these tanks.
The other 75 gallon will be a planted display tank going in my bedroom.
The 65 gallon cube has fancy goldfish in it, and that is going to go to my 14 year old daughter, who is very pet responsible and super excited about this addition to her bedroom.
The 6 40 gallon tanks are probably the ones I have the most plans for. I want to raise as many plants for sale as possible, sell them on etsy, facebook market, ebay, amazon, etc. I also plan to breed something in each tank, like shrimp, various types of fish that I have previously been unable to breed in my smaller tanks, etc.
