Both of the eyes are almost gone because it was kept with Arowana using high intense tanning light.
It's around 8-9 years old, and it got bullied by a 24" ST for at least 2-3 years. The big ST beat this little guy till it float in a corner during feeding time. Recently the owner was getting out of the hobby, the larger one got sold for around $2k+ and I got this little one very cheap for its poor condition.
And yes, I have stuffed high protein pellets into the shrimp before feeding it.
