hey payara owner notablly the Tat owners, i have a few questions. i am planning to get 2 tats and I am wondering if they absolutely need strong current. i have a large ehiem canister filter which water gently drifts into the tank with little to none oxygen bubbles. Is that safe enough?? The only other thing I can do is add a smallish bubbler. Will the tats be happy or will they die? worst of all, my dad has some sensitive hearing so when he is home for 3 days a week, he sometimes (for 2 to 3 hours) turn of my filters. Will the payaras survive? I need quick answers please!!
