"Clown Loaches are often sold at the very immature size of 1.5 inches (4cm) or so, but they should not be considered for the smaller (or even medium-sized) aquarium. They will grow quite rapidly from this cute size to around 5 inches (13cm), thereafter the growth slows somewhat, but with good care in a large tank, they can easily reach 8 to 12 inches (20 - 30 cm). They are big, bulky fish at that size. The two fish pictured were 8.5" and 10.5" body length when pictured. That is a standard foot rule beside them.
A potential owner should seriously consider the long-term commitment in purchasing a group of this species, as they will require ever- increasing size of aquaria and may potentially live at least twice as long as some small dogs.
Here are these two fish along with many smaller ones during feeding time
Adults will eventually require an aquarium measuring at least 6ʼ x 2ʼ x 2ʼ. Even small specimens of this species must initially be housed in an aquarium that is 4ft long as a minimum. Anything smaller can cause these fast-swimming fish to become stunted and stressed. "
"They are regarded as a poor choice for the beginner aquarist despite their wide availability in fish shops. They are highly susceptible to Ich if great care is not given to their acclimation or environment maintenance. It is suggested that the aquarium be designed around their requirements specifically, rather than them being added to an unsuitable environment."
