Fw Tank Okay

[NeonTetraStarters]

I have:

1 neon sunburst moon
3 peppered corys
6 neon tetras
1 plecostomus(I dunno what type. It stays very small I heard though)

Food:

Tetra Color Plus
Tetra Color Minus
Tetra Veggie Algae Wafers Extreme

I also have:

Filteration
Heating(at 76F I can't control the temp on a tetra heater
Lighting

Is this tank okay? I'm NOT putting anything else in.

Is the tank mature or fishless cycling?
