I just want to make sure I don't have to change anything I'm doing/if I should continue as I am right now. Basically like a checklist!
I've got three boys, one of which I've had for a year now, the second I've had for 5 months and the newest I've had for 1 month. All tanks were cycled properly before the boys were put in their homes.
Kiro and Kin are in their own 2.5 gal tanks, and Aki is in a 5 gal since he's a fin biter and needs more distractions and space to exercise. He has paper taped to the sides of his tanks where he can see Kiro and Kin, so he doesn't feel threatened from the sight of them (especially Kiro, he's very aggressive).
Kiro, my eldest, is a king betta, so he REALLY should have at least a 5 gallon, unfortunately we don't have the room so he's in a 2.5, still thriving and happy but he should get more space. I want to get him a 5 gal badly, but Aki needs to stay in the 5 gal at least until his biting stops. I was thinking of switching Kiro and Aki when Aki's fins are better, so Kiro can get more space. Do you think I would depress him if I downgraded him back to a 2.5 after his fins heal?
I feed each fish twice a day but very little each time. Kiro gets two pellets in the morning and two at night, his weight is healthy and the amount he eats is good for a big boy like him. Aki eats very tiny pellets so I just pinch a little in there and he gobbles them all up, though he begs for more sometimes I know not to overfeed him. Kin eats flakes because he has a very tiny mouth, and only a little bit because he starts getting bloated quickly. He's a little guy!
Otherwise I will mix up their foods every other day. Sometimes Kiro will get 1 pellet and a few flakes, Aki will get flakes and little pellets, etc. so they get variety. Sometimes I'll pop open a frozen cube of brine shrimp and feed them that for a few days.
I do 50% water changes once a week for all three tanks, also I'll scrub their tank walls with a clean sponge (no soap of course) because sometimes algae pops up. I change their decorations every month or so. I don't use any live plants but I do put in silk plants, and for decorations, I sandpaper down the sharp edges so their fins don't tear.
I have a testing kit that I just got because I only recently learned the importance of that, so I will begin testing once a week for pH, ammonia, nitrate, and nitrite.
All tanks are heated to 77 degrees F. I put a light on each of their tanks between 7-10 pm normally but I had an issue in the past with that bright green bacteria that grows in the light, treated it and it's gone now but I'm still very cautious. All three of them are very active and friendly, sometimes they hide but if you start talking they'll come out to listen to you. They are all very cute, have bright, healthy colors and full fins (except for Aki who's fins are healing from his fin biting episodes in the past, but he hasn't touched them for a month now, and they are starting to look better).
I think my babies are all doing well- I just wanted to make sure with all of you betta experts out there that I really am doing everything right! Is there anything I can do differently besides possibly upgrading the sizes of Kiro's and Kin's tanks (since I can't right now but hopefully in the future)? If you have any advice I'd appreciate it! <3 Thanks for taking the time to read my synopsis of how I take care of my bettas.
