It looks like you might be online. I'm sorry about your little guy. Do you have others? I am just about to change out a gallon of his water and put some Epsom Salt in. I'm a little nervous about it, but that's what's been recommended... along with the Maracyn treatment.
Thank you very much. I didn't see this message until now. Unfortunately my little guy passed away, but I really appreciate your kind words, and I hope your guy gets better too. I had the thought of using craft mesh like the kind they sell at Michael's to fill in the gap so this never happens again, but my husband is going to make new lids out of acrylic sheets for the tanks I guess, with holes cut for air.
Let me know how it goes for Chemo.
I just prayed for your fish! I've prayed for all types of pets... and my little Betta's sick now, so he's been in my prayers more than once in the last month or so! I sure hope he recovers 100%! Maybe I should cover Chemo's little hole with something, but he must have air too, so I'm not sure what? Screen of some sort? Mosquito netting? Fish net! All the best to you and your buddy...
