Background
I'm a noob with a 4x2 75gl aquascape tank (I know). It has a canister filter with lily pipes. The lily pipe doesn't agitate the surface more than a slight ripple. The hardscape is wood either side and a sandy path in the middle. I plan for it to be heavily planted, although it's medium planted at present (growing slowly). LED lights on day/night cycle, but no CO2. How much (if any) of that is relevant, I don't know.
Being a noob, after a 2 month cycle, I wanted fish. First (cleanup crew)- 6x Otto, 6x Amano. Second (2 weeks later) - 10 x Cardinel, 10 x Rummynose, 6 x Harlequins. Third (2 weeks more) - 6 x Corys, 2 x Electric Blue Acara.
Now, I expected the Acara to swim near the bottom, with the nano's near the top. But the opposite happened with the Acaras at the top corner only moving for food while the nano's stayed near the bottom, again fairly still. Water parameters are checked regularly and good. I therefore started to worry about oxygen. A couple of nano's died over night and so, finally getting to the point, I decide to buy an air pump (Eheim 400) and partially bury it in the middle where the sandy path disappears in the distance.
Problem
Even on low, this throws out more bubbles than I imagined and here lies my concern. 30mins. after turning it on and the fish are going mad. The acara are throwing themselves into the bubbles at the bottom, being flung up and outwards and doing it over again, while the nano's are darting into the torrent near the top and getting ejected half way across the tank. Now, avoiding being anthropomorphic and thinking they're having 'fun', I'm worried they might be getting stressed at the introduction especially as 30mins. wouldn't increase O2 levels that much. . Has anyone had anything similar and should I turn it off at night or remove it altogether?
