What size aquarium light should I get for my planted tank

The other thing you should know is that Angel fish are part of the Chichlid (sick-lid) family and as such are much like the little builders of the acquarium set. They love to move gravel around either by pushing it or by moving it in their mouths. They frequently make pseudo nests even if they are not breeding. The other thing they seem to love to do is to dig up plants. So if you are realizing plants that aren't staying "planted' then your Angels may be the culprets.

When I had angels (along with many other fish) in my 70 gallon tank I used artificial plants. The artificials today are very good in quality and not only look like real, but move like real in the water currents.

Unless you absolutely prefer to have the real plants (instead of the artificials) there is really no "huge" beneficial reason to have them. Yes they absorb some carbon dioxide and do give off oxygen but the vast majority of the oxygen in acquarium water is absorbed at the surface and is not put in the water by plants or air bubbles.

Other than that real plants don't hugely "benefit" the overall health of the acquarium, except to provide some amusement to Chichlids in something to either pull out or dig out of the gravel. If your acquarium was a stagnant pool of water then if would be a different story.

Don't get me wrong, real plants are great and look really nice also. I just got the impression that you feel that real plants are going to vastly benefit the overall health of your acquarium and that isn't truly the case at all as long as you have proper filtration, and circulation of the water by way of the filter and/or some air bubbles.

JMHO. Hope this helps.
