imo you should move the "higher grade" ones, whatever that is, into a tank without predators. I bought 3 plastic bins at big lots today to grow aquatic plants in, not sure why lol. I guess in preparation of my 55g!
I'm gonna move the predators I think...
I have a few weeks before they become free swimming..
For rimless at a less-than-ADA price your friend might look at Mr Aqua. Still not cheap, great quality and a lot less than ADA price.
I've got a JBJ Picotope but you may not want to go that small? It's 3 gallons of awesomeness, no seams at all on front or sides. I added a Catalina Nano hood, emailed them and they put the 13w 6500k bulb in at no cost. The hood is only $15, shipping is $10...for $25 you can grow anything and it looks great to boot.
