Yeah I thought so too. Thx
So for the second part of that question... Are these more a pest or more beneficial?
Oh and sorry. I did read your link. I found pros and cons. I just wondered IYHO if the pros out weighed the cons.
I've had them. They can get to become a pain but I've never been overrun by them. How many do you have?
If they did get out of hand you could introduce a snail eating fish such as a clown loach or a smaller,in most cases, more suitable option such as a zebra loach or yoyo loach.
