I generally keep mine in the 76F range and spawning I keep them at 80F.

Hey OFL, what temperature do you keep your bettas at?

Thank you so much!

To be honest...I don't have a favorite brand-I view them all the same-Plus I don't use filter on tanks 10gal and under. I do like sponge filter on smaller tanks if I do use them.
The very best filter is live active growing plants and that is my main bio-filtration on all my tanks big and small....

I just want to clear this up for myself....What kind/brand of filters do you use for single betta tanks? Thanks.

Okay thank you!

That should be fine IMO...

I'm thinking of the standard rectangular 2.5 gallon glass aquariums. Just a male plakat. Not a king or giant.

That depends on the tank shape and size, sex, and age of the PK...generally the 2.5gal is fine.....

Hey OFL, I just wanted to ask a quick question....Is a 2.5gal tank enough space for a plakat male?

Thanks,
