I have a 180g planted tank with some tetras that all seem to gravitate to one corner. Why, and how can I get them to swim around more?
I reduced the amount of food and got a little more action, but still much the same behaviour as before.
The tank is a couple of months old and the tetras have all been there for 2 weeks to 1.5 months, and they haven't shown explicit signs of bad health.
Water parameters are approx
PH 7.3
Temp 25 degrees C, 77F
GH 6 degrees
Ammonia 0ppm
Nitrite 0ppm
Nitrate 5-10ppm
Lights 6-8 hrs / day
Filtration 2x big sunsun canisters
Food variety incl frozen blood worms, bug bites, vibra bites, frozen spirulina brine shimp, guppy flakes, and some inking foods.
The tetras are red phantom, silvertip, and congo, in schools of 6, 12, 6. There are some other fish (dwarf gourami, corys, guppies) but it's the tetras that hang in the corner.
