hello everyone. a few weeks ago i went to a fish store that i had never been to before and bought a delta. at first he was acting pretty normally, but things have gotten strange...
What size is your tank? 1.3 g
What temperature is your tank? around 80 degrees (i have a thermometer), but it gets a bit chillier at night.
Does your tank have a filter? no
Does your tank have an air stone or other type of aeration? no
Is your tank heated? no (i live in the tropics so its always hot here)
What tank mates does your betta fish live with? none
What type of food do you feed your betta fish? new life spectrum betta formula
How often do you feed your betta fish? 3 pellets / day
How often do you perform a water change? every other day
What percentage of the water do you change when you perform a water change? 100%
What type of additives do you add to the water when you perform a water change? stress coat (dechlorinator with aloe vera)
Have you tested your water? If so, what are the following parameters? i have not
Symptoms and Treatment
How has your betta fish's appearance changed? his spine is slightly bent upwards, and his back has a red tint to it, unlike the rest of him which is pure white
How has your betta fish's behavior changed? he spends most of his time laying at the bottom of the tank, kind of on his side, and just stares forward. if i go up to the tank and touch the glass, he'll swim up like a crazy person and start flipping out, then go back to the bottom. i also noticed that he does not swim like my other bettas; he swims like a shark, moving his body from side to side
When did you start noticing the symptoms? about 4 days ago
Have you started treating your fish? If so, how? no
Does your fish have any history of being ill? no, but ive only had him for about 2 weeks
How old is your fish (approximately)? not sure..maybe 6 months or so?
thanks to anyone who could help. i know the water changes aren't ideal (the water quality stays good, but ive heard that 100% aren't recommended because good bacteria are eliminated) but ive always done 100% with my other 6 fish and haven't had issues, definitely none like this. OTHER than the 100% water changes, could something else be causing this?
