Presently the aquarium has 15 Neon Tetras, 4 Glow-light Tetras, 1 German Blue Ram (male) and a Peppermint Cory. It has been a healthy tank for over 6 months now with no aggression issues.
I would like to add another group of colorful Tetras to the mix but I'm not sure what would work or if I'm already approaching maximum capacity for the tank.
I have been keeping African Cichlids for the last 6 years in other tanks and am very confident with capacity and species mixing with these fish but I don't know to much about the Tetras. Any help on what Tetra would work in this tank will be greatly appreciated.
I'm wondering why the filters are being cleaned so often. Are you just removing the inserts/media and rinsing it (in water from the aquarium, not tap water which will kill the good bacteria)? Or actually taking the filters completely apart and really cleaning them? You have a lot of filtration for a 29g and with 50% water changes (that is very good, keep that up) the filters should not need frequent cleaning but only rinsing if the mulm is significant. However, having said all that, it is obvious that things are OK in your setup; as another poster mentioned rams are sensitive to water quality and keeping them at their best is not something everyone has luck with. Some also find neons challenging, and that is always due again to the water quality. So you're certainly doing things right, but I would consider less filter cleaning.
I agree with several others, additional corys are needed; they are shoaling fish and prefer being in a group. I've had good results with three of one species, and three of another, and three of another, etc; they chum around mixed up sometimes, but interestingly seem to prefer their own species.
