Yesterday I cleaned Perry's tank and she got to go in the small tank. I put a betta hammock in the big tank. I put Perry's old decoration in the small tank and she swam up to it like a long-lost friend. How funny. She was eager to go back in her 1.5 gal tank so I did a water change and put Perry in. Then she wanted to go back in the small tank. I put her in the small tank and she curled right next to the decoration. After a little while she wanted to go back in the big tank. So I put her in the big tank and she wanted to go in the small tank. So I put the old decoration in the 1.5 gal tank. Finally she settled.
Ooh! Update: My brother's friend's little brother overfed Perry! My brother's friend asked if he could feed Perry a flake so I said "Only one." So he fed one and his little brother just took some* (a lot) and dumped it in there! I couldn't get it out and Perry ate it all!! I was really steamed, mad and I told him to get out and he didn't so I pushed him out. I closed the door and locked it. I looked at Perry and she was severely bloated. I planned on not feeding her but she was lying on the gravel. I thought she was going to die! I said goodbye to Perry and I started to cry. After a little while I couldn't see Perry so I thought she was dead. It turns out Perry was hiding and her stomach was more bloated. Right now, Perry is lying on the gravel and her stomach is a little bloated.
I have Finn in that tank. No filter with him though. Ghosts are fine in uncycled tanks. They are quite tough but DO NOT PUT THEM WITH AN AGGRESSIVE FISH. What happens is that when the shrimp molts, though it may have been fine with pecking, now it is vulnerable and likely will die.
