I'm trying to choose between:
A 5 gallon - divided for my 2 boys.
Each side is 2.5gal.
A 10 gallon - divided 3 ways.
Each part is 3.4gal. I've really been wanting to get a 3rd betta. If I do a 3-way divide, I would put a female in the middle.
What do you think? I'm really hoping to go with the 10 gal split 3 ways... but I'm concerned about water circulation. Where can I put the heater and the filter so that everyone's "apartment" gets equal filtration and warm water?
Would I have to get another filter/heater for the other side?
Also, if I have a female in the middle, do I need to worry about the boys on each side getting stressed out? (as opposed to another boy in there) I'm trying to decide between DIY black acrylic dividers
(where it'll be harder to see through) and the (commercial or DIY) white mesh dividers
