I purchased 3 of these little guys from one of our friendly local fish stores. I was told they were "dwarf chain loaches" (Ambastaia sidthimunki), but based on my research it really looks more like a polka dot loach (Botia kubotai).
What I'm worried about is the size differences between these two species. I thought I was getting maximum 2.5 inch loaches, but instead these could grow up to 5 inches!
Does anyone else have experience with polka dot loaches? How big do they really get, how fast, and any issues I should be aware of? (community behaviors)
Here's a quick pic of one of them - they move quickly and constantly so they are hard to snap!
Loaches really depend on the species and diet. If you have a load of snails in your tank, they'll be full size in no time. They can hold their ground against much bigger fish, but don't typically instigate if they have enough space/territory.
I think you should be ok with them, even if they turn out to be the polka dots.
Very nice fish, love loaches.
Found these pictures of the two species in question...
First picture is a Dwarf Chain Loach (Ambastaia sidthimunki)
Second is a Polka Dot loach (Botia kubotai)
Clearly mine looks more like the latter...
I've been on verge of buying these guys a few times to keep my snail population in check. Nice looking fish! On this link here some have reported they can get as big as 6", http://badmanstropicalfish.com/stats/loach_stats/stats_loach_kubotai.html (http://badmanstropicalfish.com/stats/loach_stats/stats_loach_kubotai.html)
Oh yeah I forgot to mention - they look more like polka dots - pretty much 100% sure, especially after seeing the Latin name.
Best Loach so far is a Yo-Yo Loach, hands down.
I have one that is 4", man is it ever beautiful.
YoYo loach... any pics from your tank?
Not sure how to upload a picture.

Hey Andre,
For sure you do not have Dwarf Chain Loaches, I think your ID of Kubotai Polka Dot Loaches is correct.
The Polka Dot Loaches will generally grow to 10cm (4 inches).
In the event that they grow bigger and that causes issues in your aquarium,
I am sure there will be a willing buyer who would love to have them at that size
;)
Good Luck and enjoy their behaviour :)
Andre-
I sent you a pm with some information on Botia Kubotai from by book on loaches.
I have a few sidthimunki, one of the nicer loaches if you ask me. They stay small and show no aggression towards each other or any tank habitants for that matter. And they are active, yet less erratic then it's bigger botia cousins. They don't care much about snails though.
Hey Andre,
How are your kubotai loaches doing these days ?
Your loaches are juvenile polkadots for sure, as they mature, the yellow dots will separate more. I used to get the juvies mixed up all the time, but after I lost a $50 bet, I know better now :-[
I know those yo-yo loaches eat MTS, don't know about polkadots botia, I would think the larger botia species like clown loaches would be better at it.
