they dont even have to be an adult and they can already break
those glasses of the normal fish tank , be it a big or small tank .
just pray nothing happens if you ever keep one .
12 mm is thick and isn't all that stressed on a tank of that dimension if its been properly built, I would say that unless you get them into a pond thats about as safe an aquarium you could put them in.
Can i keep a Giant snakehead in a 6by2.5by 2.5ft tank ? Will it break the glass from its activities?? 12 mm thickness... Pls advice . will prob buy one 18 inch one from the wet market near my house . lol
12mm is too thick for 6ft aquarium and will probably break if u start with 18 inch sh. i think the aquarium wont break if u keep juvenile giant sh about 4 inch.
feed them with frozen food also can make them less aggressive.
