If you are looking at artificial rock, make sure the pieces you get does not have large holes that fishes can swim inside.
My tank fouled up becoz of that.
Fishes swam in and died inside. The water inside the rock foul up and I had to strip down the entire tank to clear that mess.
But imo, for 2 footer, better to go for live rocks.
If you are keen on the smaller pieces, I have 2.
These are ok coz they do not have large holes.
sell you cheap cheap.
Hope your tank goes well.
Mine is kindda getting screwed coz the fiji rocks that I got was really bad.
now I bet my tank parameters must be quite jialat.
