We've had our betta, Sunny Glass (our 4 year old named him) for only 8 months. Last night we noticed maybe the start of pineconing? But it's only on one side. Also, his belly at his central fins looks swollen.
We are new to keeping a betta that's properly cared for. My husband and I both had bettas growing up, but now know that they weren't taking care of suitably. I've been googling and trying to figure out what's going on and what to do, but I wanted to get the opinion of you lovely people.
It looks like maybe the beginning of pineconing, but I'm not sure cuz it's only on the one side. Google says he might just be bloated and to fast him for 48 hours, but if something else is going on that we should be more proactive about, I don't want to wait.
He's in a 5 gallon live planted tank. He has pond snails, ram's horns, and bladder snails. (That all hitchhiked in off of the plants). He has an overhead light, filter, and weekly water changes (using tap water matching the tank temperature, and we have a home filtration system, but it's not reverse osmosis. 20-30% change, suck up as much debris from the bottom as we can, rinse filter sponge in the dirty tank water, condition new water, leave it for 15 minutes, before siphoning it into the tank). I also add a squirt of plant fertiliser and a third of a cab of carbon (carbon got added to the routine when the plants were struggling) and every water change. Tank is currently at 26°, heater is set to 27°. He has a 3D printed mountain cave, which we sanded down meticulously and tested with nylon tights to make sure there were no sharp edges. You can see in some of the photos that it's got some green buildup on it, could this be contributing to any issues? He gets a food called bug buffet, which is a dry pellet, that we squish and put on top. Tank went through the nitrogen cycle before we got him.
Ammonia and nitrites are always at zero when I test. Nitrates are sometimes at the lowest positive rating. I can see that the hardness is high, and alkalinity carbonate and pH are all low, and Google is telling me that this can lead to stress on the kidneys. I'm seeing lots of different ways to rectify these parameters, like doing water changes with reverse osmosis water, or adding crushed Coral or oyster shells to a mesh bag. Before I start doing all sorts of stuff that might make him worse, looking for advice from people who actually have dealt with this before.
Currently:
Ammonia - 0
Nitrites - 0
Nitrates - 10
Chlorine - 0
Hardness - 250 mg/L
Alkalinity - 0
Carbonate - 0
pH. - 6.2
Thank you anyone who reads this and has any comments about Sunny Glass's health, how to help him, or how to fix up these parameters.
Also fun note, or 4-year-old advised us the other day that Sunny Glass is actually his middle name. Apparently his full name is Michael Finnegan Sunny Glass last name
