So I've had my bichir since I was 10 (I'm16 now) and I'm sure I'm caring for him very wrong. I got him from oetsmart along with a bunch of other fish and they just handed him/her to me and told me to just feed him bloodworms every other day. And so I did as he/she got bigger, he/she started eating all of the fish in my tank except my silver dollar. My silver dollar has passed and now he's/she's the only one in a bare tank with rocks and disgusting environment that I just can't clean. What's recommended for him/her because I want to keep him/her happy and healthy.
