Right but you can determine if the neons are big enough. I grow all winter then move them in the spring and hope, lol
Beyond geographical correctness, white clouds are really not tropical but temperate water fish, they do best with water temps not higher than the very low 70s F,
and easily take water temps in the 40s.
I would keep them in an unheated tank.
Seems like you have plenty of room for stocking if your only pushing 5ppms. Maybe let the WC go a bit longer a see how stable you are. For instance. I recently found out my pleco tank will hold 0ppm for 2 weeks with no WC, didnt want to go longer than that but defininly not as "stocked" as I thought!
The Angel's are only 3 inches and the rams are about 2 inches so I know my bio load will increase as all of them age.
I'm surprised even with a 4 inch bristlenose and a 6 inch blue phantom the nitrates are still this low.
Plants are mostly slow growing java fern but I'm assuming the large pothos I have in there is doing most the work
Fast growing plants are awesome! I keep duckweed for this reason alone, 3 bristle nose, a clown and 12 in sailfin and the duckweed eats every bit of the waste and is starting to starve my other plants as well.
Duckweed would be a problem in my tank... I had frog bit in mine for a while but it was blocking too much light and the Angel's and rummynose tetras were tearing at the roots
