My very first was a redcap named Button when i was 5yrs old. Had him in a 10 gallon tank with an undergravel filter and fed him nothing but flakes... Its a wonder he lived 3 yrs. Have learned so much since then. Why did your sister have so much trouble?Haha, well she is lovely. I bet very impressive in person!
I have a red cap oranda. They always make me think of my little sis. She loves them, but never had luck keeping them. It wasn’t till I started keeping fish myself that I found out why.
