Yes, they come out to eat.
Their tank mates includes 8 pink zebra danios (small), 1 pleco , 1 widow tetra and 4 dwarf gouramies. I've got blue sand in my tank with coral and some black and blue colored stones. and yeah, the artificial plants as well.
It's been running for 3 years now and yes, it is cycled. the water parameters are normal. It's artificially planted tank.
The 80 gallon tank I've got has aggressive fish and I'm sure my neons wouldn't want me to put them in that tank.
I've got 10 neon tetras in a 10 gallon tank with sobo submersible filter fitted in it. Among those 10 neons, 5 neons swim around the tank like they own the tank but the other 5 make a school and stays near the filter in the bottom left corner. Are they stressed or something?
