The water parameters are great, no ammonia or nitrites, nitrates are 5ppm. PH and temp are set to their preferred ranges. He has hiding spots all over the tank so he doesn't need to worry when he's out and about. There is plenty of flow. 7 loaches all up and some rosy barbs as dither fish. We've tried dimming lights inside the tank and switching them off altogether.
We're feeding pellets, blood worms, zucchini, peas, cucumber etc. No interest.
Do you have any other ideas I can try? Thanks
