55 gallon is to small??
A 40 gallon aquarium is recommended
adults can grow to 20 cm (8 inches).
ive never seen a 24 inch antenata in my whole entire life.
thats impossible.
where are u getting ur information?
I think he is talking about volitans which do get rather larger but Antennata Lionfish (Pterois antennata) are suggested only to get about 7-8 inches and recomended anwhere from 30-50 gallon tanks.
