I'm on a road trip and brought my betta so he didn't starve to death in my apartment but I forgot to bring the water treatment solution. I used tap water when changing Gustav's water yesterday, but I kept half of his old water so I thought it would be okay if i didn't have the drops for the water... about 4 hours later, he was drastically different: very pale, not moving, floating at the top (not dead or on his side of course but his little forehead was slightly peeking out of the water almost like maybe he could breath better up there??). Then I noticed his poor little fins started to shrivel and even started turning bright blue (he's dark blue) like they were getting bleached or burnt??? I rushed to the nearest pet store and bought tap water conditioner and 5-1 water testing strips. When I tested the water, the Ph was honestly not too bad, like around 7.0, but the water was super hard. The KH (Carbonate Hardness) was 240 and the GH (General Hardness) was 180...
What in the world did this to his fins?? Was it the chloromine?? I've heard the Ph can burn the fins off, but like I said, the Ph wasn't really that bad, so what the heck was it?
He is better today I GUESS, but his long back fins are definitely damaged. They're all shriveled up and he isn't swimming with them at all like he's either in pain or paralyzed or something. (I doubt he's paralyzed but he's seriously not usinig the back half of his body at all).
Will his fins grow back strong and colorful?? Will they heal?? Was else can I do?? I'm afaid to change the water or remove him since he's in such a delicate state.
