sorry about your loss i am also interested in what would be the smallest FW ray and the easiest to care for. this christmas im geting a 220 gallon with a large footprint, and was wondering if i can house a single ray permanently in it
I'm sorry to hear hun. Macy was doing that backflipping thing awhile back but then stopped and seemed to be fine for a week or more. Then she just up and passed away out of the blue. It's a hard thing to see it happening and be at the point where you don't know what else to do for them.
Don't be afraid to try again. For me, I'm waiting a bit because I'm still pretty upset over the whole thing. The 2 days before I left for vacation were spent constantly looking over at the tank expecting her to be swimming around but seeing nothing but blank water. It was depressing. Someday there'll be another. I wish you the best.
