Heyo. Does anyone have any good ideas on how to proceed with this?

I live in Finland and starter cultures for foods are really hard to come by. No store really sells them neither there seems to be clubs or that many other people who cultivate them themselves. So far I have only seen one or two advertisements from some real far away place that sell grindal worms and that's about it.

This whole situation leads me to think that I probably should try to harvest them from the wilderness.

I have read/heard about collecting samples and then cultivating them for some time & then isolating the stuff that I would want, and I was thinking of doing that. But are there any other methods that are worth trying?

Heyo. I'm currently setting up a new 20g high aquarium. The theme of the aquarium will be SE Asian/borneo peat bog. It will be genuine blackwater with near zero hardness and pH somewhere around 4 to 5.

I have done some serious research on the species I can put there and the said betta species pair is one of few that have really caught my eye and I would like to ask a couple questions regarding them.

Seriouslyfishy states "An aquarium with base measurements of 45cm x 30cm could house a pair or small group.", which is smaller than the footprint of my tank, so I would assume they are fine space wise.

So we get to the point:

How do the said bettas interact with each other and other species?

What should the male/female ratio be and realistically how many of them can I house in the tank? Like if I get a breeding pair, can I leave any of the babies and grow them, or will it turn into carnage?

Also is there any major difference between the two species behavior wise?

Heyo. I'm currently cycling my new ~20g high tank. The tank will have " a bog in South East Asia" theme going on. The stocking plans for it are currently completely open but I would like to keep genuine blackwater fish and the ph of the aquarium will most likely be sitting around 4 to 5 with near zero hardness once it's finished.

Chocolate & licorice gouramis are one of the main species that I have been eyeing at, but considering how the licorice gouramis seem to be mildly annoying to feed, I will probably go with chocolates instead.

So I would like to ask for some feedback here, realistically, how many chocolate bois can you keep in standard 20g high without it turning into completely carnage?
