i currently have a 30 gallon aquarium with 2 oscars and a pelco. I know it is kind of small but the oscars arent to big yet and will be moved very soon. But the question i have is are undergravel filters worth using? i have a filter that hangs on the back going as well. I have around 2.5 in of gravel on the bottom if that makes any difference. If i get rid of the filter will i need a seperate bubbler?
thank you,

Bubble wands are more for aesthetics imo as long as you have some type of surface agitation you'll be fine. While I'm a canister fan HOB offer great mech filtration which you'll need for messy Oscars.
