Trying to aquascape my tank with CO2 running for a week. It’s a 130 litre and wondering if I have too many fish. I’ve mainly different tetras, ember, rummynose, neon and phantom. I do though have 2 bristlenose plecs, two Siamese algae eaters, 2 pyjama loach, 8 glass catfish, 4 corydoras, 3 pearl gourami and some baby apistogramma. Is this too many?
