It's been a few weeks, here's an Ursula update!
She's doing fantastic. I redid her tank since the dragon stone wasn't working out so well, and switched it for two large terra cotta pots covered in moss. There's a ton of stem plants growing in the tank too- I keep waiting for her to start destroying them, but so far they're thriving! I just had to do a big trim of the plants since they were taller than the tank and covering the whole top. I got to witness my first oscar temper tantrum after redoing her tank! She was lying on her side pouting at me for a few minutes and then sat in the corner all afternoon. She's better now though and I think really enjoying the new setup.
She's grown so much, she's already pushing 6 inches nose to tail! Today we tried a new fun game... baby guppies. One of my female guppies who was supposed to be in lady isolation since she's got a bad spine had a whole batch of fry, so I got to test out my cull machine, and she had a wonderful time! It was really quite awesome watching her use her brain and hunt like she was built to do.
