Hello!

[Macawbetta]

Relatively new to the betta world, I'd like to introduce my two boys Barnago (my five year named him) a beautiful half moon and Hugo whom I just got , a stunning crown tail. Both I got from the pet store in town. Any tips would be great. I've had barnago for a little over 5 months and he's doing fantastic they're both in 2.5 tanks. I do water changes every week. Any idea on colours? I believe Hugo is a spoon head he's quite hunched and is probably one of the biggest betas I've bought from a store...

Welcome! Both of your bettas are beautiful, fantastic photos as well! c:
Both look to be multicoloured. Hugo could be considered a mustard gas, but experienced breeders likely wouldn't label him as that. He could also be a king betta, if he's particularly big.
Here and here are the colouration guides I usually refer to, if you'd like a look.
