I recently have purchased a weeksii bichir about 5 inches or so and he has been fine since last friday everyday he looks normal. today he has alot of whiteish or just looks like the suckerfish attacked him. i have seen it in the past to a minor extent and their are alot of other bichirs who do not have any on them. it looks bad on him im concerned what to do if i need to move him or just put in the medicine and watch him. is it common for a regular pleco to do this to a bichir that is in his home. i noticed the weeksii was in the plecos cave or castle. what should i do please some adivce to keep him alive
