Can an angelfish live with platies?

Yes.

Both are comfortable at 75–80°F.

Plan on a tank of at least 30 gallons for both.

By tank size

Below 30 gallons there isn’t enough room for both, so the answer is no.

How to try it

Use a 30-gallon tank at minimum, but go bigger if you can, since angelfish need height for their long fins. Keep 3 or more platies, with several females to every male, and add tall plants like Amazon swords so the angelfish have cover and the platies can break line of sight.

1. Set the tank to 75–80°F, with pH 7.0–7.5 and water hardness of 10–15 dGH, the range both species are comfortable in.
2. Add the platies first, at least 3 with several females to every male, and let them settle in for a week or two.
3. Rearrange the plants and decor just before adding the angelfish so no territory is already claimed.
4. Add the angelfish last. Feed the tank first so everyone is busy eating, then watch for the first few hours.
5. Keep watching closely through the first days. Brief flaring or a few chases right after the angelfish goes in are normal.

Warning signs in the first weeks

• Torn or split fins on either species, especially the angelfish's long fins, or any wounds, missing scales or bite marks. Separate the fish immediately.
• One fish being repeatedly chased, cornered or pinned against the glass, plants or decor. Separate the fish immediately.
• A platy hiding constantly near the surface or in a corner and refusing to eat, which suggests it is being harassed when you aren't looking.
• The angelfish claiming one part of the tank and driving the platies away from food or open water.

Backup plan: If you see any injury, or one fish is repeatedly chased, cornered or pinned, move the aggressor or the victim to a separate tank right away; don't wait to see if it settles. Once they are apart, rehome one species or keep them in separate tanks.
