.... hey, um, guys?
There's something I need to tell y'all.
I have some..... GOOD NEWS!!!!!!
Tian-Tian and Taco both seemed to magically heal overnight; I did a thorough cleaning of Tian-Tian's tank before I left on my trip, and he's back in it now, swimming all over the place and just as healthy as ever!
Augh, after so much worrying and trying my darndest to get Tian-Tian better, he's back to his normal self. Even Taco seems happier than usual! I don't see any fungal symptoms from last night; perhaps I was so tired from my trip that I was mis-reading my boy's reactions to me changing their water. After all, I did come home in the middle of the night, haha. They might've been sleeping for all I know!
Anyway, so after much trial and tribulation, my boys are back to normal. *throws confetti*
Thanks to everyone that helped and for all of your support!
So my next step is to invest in a bigger tank for my boys; Taco has outgrown his little 1 gallon already! Goodness me!
