Oh yes I went round with the black duct tape taped the lid on and every hole at the back just a half inch slot for the filter water to get in. If it makes it out their it deserves to walk the world as a human. I had a gar in the past that kept me on my toes plus a grass snake that I never seen again so I’m a little cautious. When I get the new tank I’m gunna make the stand and a cover lid to match furniture plus I have 3 kids. Explains itself really. So while I have you the fish I’m considering in the thread do you think they would be ok? And is their any others that would suit the Arowana better that I can corporate. Or even any decor it likes? Google can only go so far I’d rather ask the people who know. And thankyou for all your reply’s I’ll get the new tank once I finished working away.
