so i have 7 kuhli loaches but i have gravel and have noticed a few of them are how can i put it fading in colour i guess. looking sort of worn on the sides, i realise now i shoudn't of purchased these fish when using gravel. im thinking there trying to squeeze into places they aint getting and rubbing against the gravel. so in short should i give them away as i think changing to sand would be too stressful and not good for any of my fish.
Thanks James
I have Khulis with gravel. There are plenty of pieces of wood in the tank and they just hide under those.
I used to have sand in my tank, and really didn't like it. Main problem was that when I used to clean the algae off the glass, a few grains always seemed to get stuck between the magnet and the glass and would result in scratches.
Perhaps you could make a small area of sand in one of the corners?
