Good to know!I'd be careful of that petsmart center piece you have, i had one and the water gets inside and will start to smell unless you throw a bubbler in it to circulate the water it turn stall inside
My Bichir actually went missing and finally realized he had found his way in there through a tiny hole. I had to take it out of the tank and drill out the ends with some large holes and finally was able to shake him out. He's been fine since and now goes in and out as he pleases lol!
