Hey guys, i have 6 tetras in my 10 gal right now 4 head & tail lights. 1 serpae and 1 lemon tetra(i think it is). I want to get either 3 cories or maybe a gourami. Do gouramis do okay alone? also with the serpae should i worry about fin nipping. He hasnt been nipping yet and hes been with the H&T's for a few weeks. i want some more color in my tank thats why i was recently thinking about gouramis. any other recommendations would be awesome!. thanks
