Well, today we went to Petland to get live rock. Got 8lbs. of figi for $7.99 a pound with about 20lbs. of base rock at $2.29 a pound. While we were waiting on the fish guy that was helping a lady that was trying to decide which angelfish out of the remaing 2 that she wanted.......we looked at their display reef and my mom saw a goby and liked it so now she wants one. My question is, is there a goby that I could put in a 20g with 2 percula clowns, or is that pushing the stocking limits? Another question, Petland had coral that was 60% off like they always have when I go in there so I decided to look at it for once, some of which that I liked were duncans, BTA's, mushrooms, and zoanthids can I get all of these with my lighting when my tank becomes mature?
