No.
My reasoning behind this is that if you don't know where you'll be or what you'll have in the future you cannot plan for an upgrade or ensure the loaches' futures. Even if you think you'll have a suitable tank, you never know what might come up. I'm personaly completely against keeping any fish in an inadequately sized tank unless you already own the tank it will move into. Even though the fish is small now, it isn't fare to put it in a tank that won't be large enough for it at maturity only to find that a few years down the road you can no longer keep it resposibly. Re-homing a 10" clown loach is difficult to say the least.
