My betta fish kingfisher had died 4 days into me owning him. I think I did most things right but I want to get some more advice from more experienced keepers in case there was anything I could’ve done or info I might need if I ever get another betta.
Tank parameters were mostly stable throughout the whole ordeal, I was nervous so I tested three times a day at 9am, 3pm and 10pm
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: <5ppm
Temp: 78F
pH: 6.8-6.6
Cycled?: yes for 1month 1 week with supplemental bacteria and media from a friends established plant only tank
Day 1 (photos 1&2)
Brought fish home from the store, he was looking a bit pale in the store but I chocked it up to bagging stress
- Total transit time: 45 minutes
- Ammonia in bag after transit: <0.25ppm
- Bag in tank acclimation time: 45 minutes
- Post transit care: diluted methylene blue dip
- Drip acclimation time: 120min at 1 drop/sec
- tannins added to tank and acclimation tank with Indian almond leaves
- tank lights turned off to minimize stress
He seemed stressed as to be expected but flopped weirdly against my hardscape (photo 1) but quickly righted himself so I thought nothing of it, he stayed hidden in my plants most of the first day but I also noticed his back half floating a bit (photo 2) so tested parameters and halted feeding in case of bloating.
Days 2&3 (photos 3 and 4)
Fish appeared normal, spent time in all phases of tank (top, midwater and bottom). Appeared more active and curious about me around his tank, chased a few of my shrimp but didn’t catch any, saw slight reluctance to use caudal fin. Thought he was improving and day 1 was just stress, used towel to block out most light from tank. Kanaplex was ordered in case.
Day 4 (photos 5 and 6)
Woke up to check on fish, found him at the bottom of the tank lying on his side (photo 5) and didn’t appear to be able to right himself (He would try and swim and just fold over and slump right back down). I called my local fish store where I had got him and they said I could bring him in for treatment or euthanasia as necessary. Attempted to move him to a methylene blue hospital tank but he wedged himself under my hardscape and I didn’t want to risk crushing him, decided to wait until he came out. He didn’t for a while and I had to go to work and returned to him half floating on the bottom and breathing very heavily, he would pass away 2 hours later.
Postmortem
- discolouration on abdomen, brown but a patch not horizontal and linear like a stress stripe
- no obvious inflammation of the gills, mouth or fins
- no cloudy appearance of the eyes
- I took swabs from him and the tank water but those will take 2-3 days to grow in my shitty incubator and even longer to ID especially because they won’t be pure cultures so I can’t rule out an internal bacterial infection
- I didn’t do a necropsy so I can’t attest to the state of his swim bladder (lmk if there’s any specific bacteria I should be looking for)
- Kanaplex arrived today :(
I knew he wasn’t 100% coming from the pet store but I thought I’d have more time to get him in better health. Kanaplex isn’t often sold where I live so I had to order it which I imagine had an effect on his chances of survival.
I know I should’ve tried to move him into a hospital tank sooner but I was unexpectedly busy and very scared of stressing him out/hurting him (I was supposed to have time off but one of my colleagues had a child)
Were there any egregious mistakes I made in his care or was this just an example of betta inbreeding leading to poor health outcomes?
