my observation has been that the growth is very fast until they reach about 1.7in-2in, then the rate really drops.
My largest is approaching 2.5" now, and while still growing, it is barely measurable.
This is consistent with their max size of 8.5cm=3 1/3 on fishbase: most of them will reach about 3/4 of the max which is very close to 2.5" you see. In other words, your loaches may be already full grown.
Some other sources give 4" for the max size; seems to be an error.
And, incidentally, the growth pattern seems to be closer to barbs than to clowns; this may imply that the lifespan of polkadots is close to that of barbs (8-10 years max), much less than for clowns.
HTH.
BTW, in my tank polkadots win over (larger) clowns every feeding.
