I am taking care of my nephew's fish Beatty. My sister brought him over last Saturday and said he didn't eaten much (maybe a couple bloodworms) over the previous week. She suspected two things: 1) she didn't change his water soon enough, as it was a few weeks (1 gal tank with filter); 2) the temperature of the water got too low one night.
Beatty continued to not eat at my house. He looks at the food like he's interested, but then darts away. Because I have a cold house, I moved his tank into my closet with a lamp (it also had natural light from a sola tube), where I have a heater to prevent mildew. The water is staying consistent at 76 degrees (but I feel a little bad putting him in there!) I talked to someone at the pet store who suggested frozen bloodworms--to throw a cube in there for a long time and see if he eats. I can't say for certain he didn't eat anything. It seemed like a bad idea b/c it clouded the water and Beatty then hung out at the bottom of the tank. Subsequently, I changed his water and added 1t/gal epsom salt on Tuesday night. He has since perked up and acts interested in food, but still doesn't seem to go for it. I also tried pellets and thawed bloodworms.
My sister will fetch him on Sunday, but I am wondering if you all have any thoughts on this. Thank you in advance.
