I'd love to see for your tanks:
10 gallon: male, with java moss, java fern, and ahryd low light plants, with a few hidey hole ornaments, fabric/silk plants, soft plastic plants, and ghost/glass/cherry shrimp. Why so much stuff? to keep the shrimp alive! xD
Ky will stay alone?
The "other male/female" with 2 ADF frogs, with floating plants, some ferns, or even some sword plants, and hidey holes. ADF may try to nom the betta's fins, so feed accordingly and allow coverage :)
or with the 10 gallon... Wanting a sorority... 4 females minimum. I had: Marge, Tina, Rose, Zebra. With a 10 gallon it's easier to find them all xD I have some females together in the 40 gallon and it sucks lol. Anyways, TONS of plants!!! floating, tall, short and ones for the middle! Ornaments too, to hide in and break the line of sight. You wanna shove it full so you can barely see in it... It's more costly, more dangerous, including the fact you need 4 tanks to quarantine all females for 2 weeks, and need a couple at least to remove females who are aggressive to a point they can murder or severely hurt the other females.
