LifeOfAquatics Posted March 18, 2021 Share Posted March 18, 2021 Would a lawnmower blenny work in a 20 long? I’ve seen that they need a 29 but a 29 has the same footprint as a 20, just a height diff and the LMB doesn’t really even need height so would it work? this tank will have a few other fish and snails and shrimp along with coral. thanks in advance!

RoyalGramma001 Posted March 18, 2021 Share Posted March 18, 2021 I think so but make sure you have algae sheets for them to eat. Quote Link to comment
Clown79 Posted March 23, 2021 Share Posted March 23, 2021 Ya but they get big and need lots of algae to survive. Also depends on your other choices. Quote Link to comment
