Once again not starved. I feed all the fish in that tank at 9 pm EACH AND EVERY SINGLE NIGHT! He usually eats the shrimp. He will eat at least 3-2" shrimp every night and Silversides too. I was thinking internal parasites when I bought him too. He was treated with Prazipro twice before. If it doesn't eat as much as he should then that's not my fault because the food is presented to him every night and he gets first pick because he is so fast-usually the first one there. Although he did freak out a few days ago when I cleaned the tank with a new scrubber and has been scared of me ever since then. Before he would actually come to the glass and sit at the top of the water waiting to eat. If it really happens to be undernourished then maybe the buyer can make it come around. They are only in a 75 gallon tank. I have a 180 waiting to be filled but Im going to use the 75 for a diy wet/dry. You can see my posts for the stand and tank and another for the wet/dry in 2 weeks or less. And back to the topic-would you like me to post pics of the other fish in the tank? The Arrowana has a good shape to him. My 2 - 18" Eels are nice and thick. The Clown Loaches are very good too.
