This tank has been set up for 1 year & had 10 platys in it. I had to give them away 6 months ago because I couldn’t deal with all of the babies. I restocked my tank with 10 peppered cory catfish and 9 glowlight tetras. I’m just wondering if I could add one more glowlight or would it be pushing it?

my weekly tests results are perfect and I haven’t had any problems with my water quality etc. I’m running two aquaclear 50 filters on the tank.
