She's about 4 months old and is 23g and I'm feeding two f/t pinkies once a week since I got her 4 weeks ago (the pinks are on the larger side). The first feed I gave three but realized I was most likely overfeeding her and backed off to two. All of the pinks are from the same batch I bought at a show. My other corn is 2 months younger and her stool is pretty firm.

She's soooo tiny looking I was unsure she'd be able to take a fuzzy as she's about 1.5 cm at her largest point.

Thanks for the feedback! It does completely look like she's spraying mud everywhere so maybe this is the issue. Besides this one things she's an absolute doll and seems to be thriving.
