Random question because i cant post yet, recently aquired a rbp that is 3 yrs old. hes in a 55 g tank with the water being 84 degrees. he hasnt eaten in 6 days. the lady i got him from had 6 comet goldfish with him. yes i know goldfish is no bueno but shes had him for 3 years i figured hed be used to it but nothing not even a nibble. i understand having a piranha is a whole nother ball game but im excited. the water is fine no debris on the soil i used and 50% of his water is the water she had with him. he seems happy his breathing is normal, he is missing some teeth i guess. How long do i have to be patient for . someone said their fish went 2 weeks before, what is a dry spell and how can i identify it?
