Yeah! My water looks apparently perfect! Or that's what I thought, I'm still figuring out what the heck is causing illness in them. Because my snails thrive, my plants thrive, but my guppies don't. I've lost another one recently. I think I finally found out what was going on, I started to see tail rot in one of them so I started Maracyn's emergency treatment immediately and he started to get better! Still has a short tail but has energy, swims with his tank mates, and eats, I have high expectations of him. Yes, they give birth to live young but I have never bred them, maybe in the near future. Guppies are really beautiful and colorful fish to watch, but they are sensible. I recommend The Guppy Channel on YouTube and also Cory's Aquarium CoOp videos about them, they are his favorite fish! I am rewatching all of that to keep learning because I'm determined to have a guppy paradise.
I have a red guppy named *Canijo*, which means *bully* in Spanish haha, he is terrible with some tank mates sometimes, he likes to chase them and any weak fish he finds. Is my fault he turned like that because I did a fish-in-cycling when I bought him and he was alone for a long time, he became territorial. If you wanna get guppies, PLEASE CONSIDER BUY THEM IN GROUPS!! Don't buy them alone.. I also have three Endlers, a mini guppie's cousin
I have read your story, I'm really sorry about your Danio he looked as beautiful as your other fish. I would love to have Glofish one day. I think that to be more successful and not buy any medicine everybody tells us to use, we must research for common illnesses of the fish species we are keeping and just buy the necessary medicine which helps us to prevent and treat that illnesses.
One of the things I have learned from this hobby is that EVERYONE HAS ITS OWN METHODS to do fishkeeping right, sometimes it will be common, and sometimes not. Each tank is different and each hobbyst too. Don't be desperate or act impulsively, choose carefully the method that you feel could work for your fish. And while we learn, everything results better if we move slowly and steadily.
Thank you for reading if you get to this point!
