Your females look to be big enough to me. I would move all the females to the 40 and leave your ailing female in the 1 1/2 gallon. Housing those females together in such a small space with no plant cover is a bad idea. #1 reason fish get sick is stress. Even juvenile bettas need more growing space than 1 1/2 gallons. If you really don’t feel comfortable moving the other females to the 40 gallon you can pick up a cheap storage tote of 10 gallons or more and house them in that for a few more months, toss some fake plants in there with a filter and a heater. Space issue solved. Bettas are shade loving fish. The really will do much better with any kind of plant cover. Your koi female was probably being bullied in the 40 with the other female. The nips in her tail fin indicates that there IS some chasing and nipping going on. I hope you can find a good balance with the fish and tanks you have set up. Keeping groups of females together is always a roller coaster. I’ll be moving two females out of my sorority today actually because of issues that just cropped up. They are fine for a few months and then dynamics change and I have to re evaluate the tank and the females to see the problem.

@X skully X has given you great advice. It's entirely possible to keep a single betta in a 1.5 gallon if you are vigilant about water maintenance and parameters, but four fish that size is 300% overload, let alone 4 female bettas and no plant cover in a tank that is more vertical than wide. That's a bomb waiting to go off.

I'm not clear about some of your answers in the questionnaire. Are those water parameters for the 40 g or the 1.5g? Zero nitrates? What sort of test kit are you using? Same question about the 25% water change every other week--which tank?

Also agree with X skully X about cutting out the salt with water changes and salt sensitivity for cories.

Flake foods are not recommended. Good quality pellets--Omega One, Bug Bites, NLS etc---and frozen foods (not freeze dried) are greatly preferred.
