Hi all, so I'm setting up a new tank for an amazing looking betta I reserved on impulse (no regrets ) the tank he is in at the shop is filled with mountain minnows and he seems to unfazed which is brilliant. Therefore I wanted to take some minnows too. However after doing a bit of research it seems that these minnows are not keen on the higher water temp betta's enjoy. Any thoughts too this? Or am I reading into it too much?

Thanks in advance !

WCMM are a cold water fish, they can withstand very low temperatures below tropical fish species, making them incompatible with bettas, as they require much cooler water than a betta would like.

If you put the betta at a preferred temperature of the minnows, the betta would be lethargic and extremely vulnerable for disease and other issues.
If you put the minnows at the betta temperature, they would have an extremely sped up metabolism, causing them to be a lot more active, or they may have issues as well, which can quickly shorten their life or even kill them.

Never greatly alter the temperature of any fish to accommodate another, just because they have a range of preferred temperature doesn't mean you should house them at the absolute lowest or absolute highest that they can stand.

This was my thought yeah, I want both fish to be comfortable and happy not just surviving, thanks for the feedback, I wonder why they are together in the shop, seems rather odd for a professional shop.
Thanks again!

Also is there any similar sized tank mates you could suggest for a betta?

You can have 6-8 in the 10 gallon with a betta. Add the betta last though.

So the betta is less likely to be aggressive to the tetras and not establish a territory first.

Yes just a betta in a 5 gallon with possibly a few snails and shrimp but no other fish.
