Ok, I better not try that ever

Yes, have heard that as well about them indicating problems with the water/substrate if seen during day.
Think I only had them once in a tank ages ago, but thank god they never multiplied that much it would have posed a problem. I remember though that I once bought a small used tank that came with gravel, and there were countless numbers of shells in it, so i can imagine.
Maybe they are just too small for the loaches to eat them?

Do the bigger loaches crush snail shells or just suck the snails out? My tiny ones would do the latter. When i kept them in the Oscar tank temporarily I couldn't provide them with snails anymore cause the only time I tried, the Oscar would gobble up the big snails including shell before they reached the bottom, and he seemed to be feeling really unwell for a day. Still wondering if a x-ray would show an Oscar skeleton and two snail shells. (*if* and *would* don't go together well but I can't come up with anything sounding right to me.)
I should stop thinking about clown loaches, it makes me want a huge tank! But still like the idea of delboybully working out his phone software
