HI , I have a 29 gallong tank set up for 6 months , great water perimeters with live sand . I have a clarki clown , a ocellaris clown , they both get along great, a feather duster and some snails. I am interested in adding 1 more fish to my 29 gallon.I would like a dwarf angel of some kind leaning towards lemonpeel but I am not sure since I don't have live rock. I would feed blanched veggies and keep seaweed selects and algae clips available and even considered adding some kind of plant. I am wondering if it would be possible to have a dwarf angel without live rock.
