I have questions about the scalare angelfish

At the fishstore I go to to buy fish they said that in a 20 gallon tank I could get 1 angelfish who would be happy and non-agressive. I tried it and it worked out. however my power went out for a week in freezing weather and my angelfish died. Now I have re-started my tank and am thinking about doing the same thing. Now I have 6 cardinal tetras and was wondering if the angel would eat them? Some people say yes, some people say no, and my friend has a 20 gallon with 1 angel and neon tetras, so what should I do. Thanks.

No reputable or knowledgeable retailer would recommend an angelfish be kept in a 20 gal, singly, or with small tetras, much less all three scenarios together.

Exactly, Quantum. Scalare Angelfish can be kept in a breeding pair (alone and in a 20" high/25g tank minimum) or in a group of 5 or more (55g minimum). You can click the shaded name to learn more.

Think of it this way- imagine keeping a fish with a fin height of 10" in a tank that is only 12" high (20L) or 16" high (20H), not including substrate. That's no way for a fish to live. Sooner or later, problems WILL arise.

Also, there's always a significant chance that small, torpedo shaped fish will be Angelfish dinner. It all depends on size. You can pretty much count on Angelfish eating anything that will fit into their mouths.

There is nothing wrong with having a single angelfish in a 20 gallon tank. For a pair, I would recommend a 30 gal. In terms of eating other fish, angelfish will eat very small fish (fry) if they can easily fit it in their mouth, but typically smaller fish are faster, and can escape.

Hard to tell without knowing your water parameters and without pictures of the fish. You should know that all fish that have been in the same water as the sick ones will likely get sick also.

With respect I must disagree with your first sentence. Aside from emergencies, or specifically housing a breeding pair, angelfish should be in a group of 5 or more, and that means a 55g (4-foot) tank minimum. Angelfish are shoaling fish, same as discus, and they develop a social structure within the group. You can read more in our profile, click the shaded name Pterophyllum scalare. Keeping a single angelfish in a small tank (and a 20g is too small if the fish is to develop properly) is denying the fish something that is programmed into its nature, and this is something I do not condone.

I do agree with the small fish being eaten. As angels grow and mature, they will naturally look at small fish as possible meals. Tank companions for angels are best when they are more disk-shaped rather than torpedo-shaped, as Mina mentioned. I personally know aquarists who have had fairly good-sized neons and cardinals eaten by mature angelfish.

There may be an issue with differing water parameters/conditions and this is difficult to pinpoint without more tests. But your comment on bullying is pertinent regardless. Once a group of angelfish are in a given aquarium, new angelfish should not be added. Some have had success by using a different tank for the larger group, or re-arranging the aquascape in a major way to create the perception of a new "space." But a group of angelfish will naturally form a hierarchy and one male will usually be dominant. The group sees the tank as "their space" and any newcomers will often be driven away; in the confines of an aquarium, this often results in the death of the new fish since they cannot escape far enough from the territory of the original group. This is set out in our profile of this fish, click on the name Pterophyllum scalare.

Byron,

I agree with what you said. I certainly wouldn't set up a display 20 gal with a single angel, but if I need to put one in my hospital tank, or If I'm quarantining a single newly acquired fish, they do fine by themselves.
