How fun, to set up a new tank. The bosemani rainbows are one of my favorite rainbows. They get 3-4 inches as adults with the male being the most colorful. They are quite active fish and like to swim in mid water colum. The glass cats are a lot more reclusive and like to hide and school in the plants. Both will leave your plants alone and both will eat inverts that are small enough. I hope this helps.
