Anyone recognise this pleco

Hi i am totally new to the forum and just moving from coldwater to tropical
I recently bought two really small bristlenose plecos for a big planted aquarium and they are still in my quarentine tank growing

However one doesn't look like a bristlenose to me!

Am i wrong? Any ideas?
I am worried it might grow into an enormous fish. It is sitting beside a sewellia because they are in quarantine tank too.
Thank you

Well, I'm not an expert, but that does look like an immature bristlenose to me. Your hillstream loaches are cute.

That is reassuring thank you! It is just the other smaller one is spotty. New fish to me... should i expect lots of pattern change?

The middle photo is of the smaller i hope bristlenose pleco... still spotty

I put the sewellia pictures on because you said you liked photos on this forum.

This is my wee lockdown project... from the first lockdown... my quarantine tank. I got three sewellia lineolata delivered back in the spring... then added three smaller ones in the summer. When i did that they spawned and the fry are amazing... many don't make it but i have about 20 now maturing nicely at different ages.

Of course now i cant take down the tank.. too small to catch easily.?

Thats my excuse! Sits in the edge of my home work space and cheers me up!
