my 12" ornate is always hiding in the amazon sword forest. i hardly ever see it. its fins are pirfict so it isn't getting picked on, it may be the one picking on my other bichirs as their fins are nipped. i don't get it. it used to chill alone under the fx5 intake, but latly it has gone into the forest. it comes out only after dark. anyone else seen this hiding done at this size? when should it stop?
