You're surprised? You suggested a single clown loach as nothing more than snail control.
It's a pet hate of mine. Botia are smart, social fish who form bonds and hierarchies. They need a group of six or more to be happy, get way too big for most home set ups, and I think it's cruel to buy a fish solely to do a job for you, with no concern for its needs or welfare, either in the short or long term.
And this is a ten gallon tank...
But it's an old school suggestion for dealing with snails that still gets suggested to beginners, and I don't understand the thoughtlessness behind it. What are they meant to do with this clown loach once it's busting out of the tank? Potentially bullying all their other fish? Unhappy because it has no other clown loach company?
There are far easier ways to deal with unwanted pest snails that don't involve animal cruelty.
I also don't read every single thread, but you're not the first angry react I've left, nor the last I'm sure.
