marble betta

I just got home and my Betta is acting really strange.. A little backstory: I have 2 Bettas that used to be in a divided 5.5 gal tank. They were like that for about 3 months. They were happy as could be until I got a new divider which was see-trough and both of my fish started biting their fins...

Hi peeps! This is the first time I've made a new post in like 3 yrs since I joined this forum ><. Neways, I bred a pair of blue/orange/white marble HMPK in May, and this spawn has proven to be exceptionally successful and now I have more than 400 healthy and beautiful 10 weeks' old fry. This is...
