Any giant plakat advice?

[Henday]

My boyfriend and I are thinking about getting a giant plakat, but a lot of pet stores aren't super knowledgeable about them in my area so I'm looking for some advice. Right now we have a male beta in a 3.5 gallon that we've had for about a year, so we're good on the basics of water chemistry, but I'm wondering about tank size, amount of food needed, etc. Any help is very appreciated!

PS, here's a picture of the beautiful boy we have right now

Treat him like any other Betta just bigger,

Tank size 10 gallons,

A Bettas stomach is about the size of its eye as you know so go by that to start with.

Be warned giant Bettas grow Big

Just kidding.
