Suggestion for nano tank mid ground plant
I'm trying to find a mid ground plant for my 5G nano tank. Attached is a poor picture of the tank (taken with my Blackberry) from about a month or two ago. Please note that this tank is laid out sideways so foreground is the left side of the tank and background is the right side of the tank.
Currently I have two young amazons (not sure which species, it was given to me) and some crypt wendtii serving as my mid ground plants. Both of them seem to be getting too big to look good anymore and I'm trying to find some nice replacements that won't outgrow the tank like these did. So far the only plant that's made my list is Cryptocoryne wendtii 'Tropica' since it apparently lies almost flat on the bottom and hopefully won't get as tall as the normal Crypt wendtii that's already there.
However, I'm wondering if there might be any other plants that I should consider. The space requirements is about 4 inches wide max and about 4 inches high max. My lighting is medium, equivalent on a larger tank to about 2 watts per gallon. No CO2 and flourite for gravel with regular fertilization in the water column.
Btw, it's a bit hard to see from the picture but crypt balansae plus some soon to be added corkscrew vals act as my background plants on the right side of the tank.
