also if your up for even more differentiated constructive criticism, I got some more.
The stocking I just noticed in that tank, guppies, could be better since its such a good looking tank! you'd want good looking fish to, (guppies IMO are the lowest level to me, coloration on them IMO looks fake as all get out) maybe some emperor tetras so the blue constants against the other colors of the tank. maybe a large school of cardinals or something. idk, stocking could be better IMO, hope you benefited from this comment lol
