HELLO i have 3 sucker loach and they seem to be growing quite fast just out of interest how big do they grow

Depends what type of 'sucker loach'.

But if it's the most common 'Chinese algae eater' they can get up to about a foot long.
Most of the time they only reach around 6 inches though.

By the time they are six inches, they stop eating algae and turn into aggressive fish that attack other slow moving fish like goldfish, angelfish and the like.
