Do you know any foods that may boost the coloration of a pima?
Anything with canthaxin or any variant of it. Sometimes you can find it in a powder form and mix it into the food if you have been able to switch the arapaima to something like a Mazuri Gel diet (which is a great food for them by the way).
Also, things like clam, shrimp, krill etc...Just be careful with clam - high calcium levels can cause other issues. Also try and feed fresh shrimp with the shell on them (people peel the shell all the time, and it's throwing away good stuff).
As for the following post:
In the 75 gallon example - the tank was too small reguardless of the fish's size, so it wouldn't be important to ask it.
Not flaming so much as putting out facts. When it comes to this particular fish, few have had success. And failures are all noted so they aren't repeated. Learning from other's mistakes is very important in the fish keeping hobby. Normal fish keeping rules do not apply to arapaima. They grow faster than almost any other fish I've ever seen in captivity. Metabolism at a young age is key in it's proper care - and housing one is not something the average keeper should try. Diet, enclosure and day to day care can be life or death every step of the way, and there is very little room (if any) for errors.
It sucks to lose one (nothing like having a 12 foot long fish die in your arms, trust me, I've been there) - so we are trying to prevent it from happening to others.
