I assume you are looking at a 15 tall, which has the same footprint as a 10g but is just taller. try and find a 15 long, you have the same height as a 10, but more square footage to plant. i use one for a shrimp only tank and with ADA AS and 36w pc, I can get most of the mosses, HC, Downoi, and even eroicoulon (sp?) to grow well. i saw that you wanted to try high light stem plants, but in a tank as small as a 10 or 15 they will outgrow it in no time. I would stick to the shrimp only tank with some nice plants versus a high light stem planted tank, just my opinion of course. good luck. what type of shrimp by the way? I have CRS, and mine seem to freak everytime i try to add ferts, so for now its just co2, whatever is in the AS and shrimp/snail poop for the plants. growth is slow but everything is nice and green.
