So a few months ago my girlfriend bought me a silver arrow, he has been doing great eating every day growing, but this morning I wake up and he's dead. I noticed yesterday something was a little odd tho, he was spending a decent amount of time in the middle of the tank and when he did go to the surface he wouldn't swim his normal laps he'd kind of just sit and swim into the current from the filter. He's eaten freeze dried shrimp and blood worms since I got him, I started feeding him larger ones from a different company a few days ago with the heads on them. On the small ones I'd give him the whole thing but I always took the heads off the bigger ones. He also ate a cut up cichlid cube the other day (intended for a baby red tail catfish in the tank) and he did not eat the next day but I just figured he was digesting so didn't think anything of it. Anything will help trying to prevent this from happening again (was my favorite fish so I'm going to get another), if theirs anything you can think of please let me know.
