Ammonia and nitrite are back at zero thank the Lord!!!!
Did a huge change to get nitrate back down however today I've come in and notice there is fin damage to my Betta, this also occurred before I was away but had re grown I used melafix for a week then found out I shouldn't use this with fighters so I stopped.
However today it looks like his back fin has gone through a shredder, I have only silk plants and I genuinely have never seen my cardinals even go for the fighter.
Now the ammonia and nitrite is under control I was going to add more cardinals to make them more of a pack, would you recommend this or should I get something else more compatible (I don't want shrimp) lol
