These photos are really bad but I just wanted to show what abuse when young can do to a bettas body.
The top is Play Dough, my PK boy I got at around 6 months from work and I’ve had him for a year. I’ve taken good care of him, and varied his diet a lot, more so than my other boys (when he was younger he caught and ate a good amount of fruit flies). His body is full, muscular, firm, and his fins are great.
Below we have Bucket, my rescue from one of the nastiest betta bowls I’ve ever seen. It’s hard to see in this photo but his body is shaped more like a ball on a stick, he has very small muscles and his fins are kinda melted together after he recovered from fin melt/saprolegnia. You can clearly see his swim bladder further down on his body.
I’ve had bucket for about 9 months. They are both in the same divided 10gal being given the same diet and care. But Play Dough is in much better shape!
Neglecting a betta has life long effects on them.
