Figure 8 Puffer Fish

Hi!! I'm new to this site but I was wondering if anyone knew anything about figure 8 pufferfish specifically when feeding them. I noticed when feeding them shrimp brine from a bottle it will make their belly big in different areas, not just one even round belly.







does anyone know why this happens ?? It doesn't happen when it's fed live snails/ shrimps. Just bottle stuff.



Thank you!!!

Interesting. Not sure why that would happen.

Pictures might help.

Thats normal - same with my red eye puffers, its where their stomach is that fills with food before going through the digestive tract
