This is true, but lacks a little background. Clown loach's can reach 12+ and ideally should be put in a 75+ aquarium. Must big box pet stores fail to pass this on as they want to make a sale. All loachs should be in a group of at least 5 or more to maintain a healthy life. These little guys have quite a personality and you will truly see this when they are in a group. Failing to make this change will most likely stunt the growth of the fish and lead to a short life term.
You have an extremely nice aquarium and we look forward to seeing more pics as it changes with time!
