Because right now it's a juvenile and I'm working on getting a 75 gallon tank for him then I'll get 5 more
But my point is, right now, there is a good chance he is not happy. Also, what if you cannot quickly aquire a 75g and that clown loach gets bigger? He will become stunted. And he will be damaged. And his life will be shortened. I had a clown loach in a 40g tank and I rehomed at 2 inches long because this was a concern of mine, and as a responsible fish keeper, it should be a concern of yours too. I had only had him a few weeks before the members of this forum told me I was wrong. I am not trying to ride your case, it is just that this kind of reckless regard for the well being of a pet just gets to me. I know I have not been perfect at this, and I have made stocking mistakes. Heck I had to rush setup a 55g due to a stocking discrepancy. It happens. But you have many people telling you what this fish needs, and you are blowing them off.
I understand that you think he is okay now in a little tank, and that you have time. But it is best to put a fish originally in a tank that will suit it as an adult. This way you do not risk stunting the growth of the fish.
