I'll see if I can get pics sorted at the weekend - one kind looks like the ones that are surface surfing in the pics on the thread I was looking at!
I'm not convinced I've been overfeeding, but there has been quite a bit of algae for them to eat. Don't get me wrong, I do like them and if they are doing no harm then I'll leave them be and just pick a few out every now and then. On the other hand, if they are doing harm to my plants then they go! If I don't fancy a shoal of loaches, would a puffer do the job?
Cheers,
