      What to watch in the first two weeks

      Compatibility on paper is only a starting point; the first fortnight is where you actually learn how these two get on. Add the established or calmer species first, give the tank a few days, then introduce the other — and keep watching, because the early days reveal more than any chart.

      • Feeding time — watch whether one species muscles the other off the food. A fish that consistently misses meals is the one that quietly fails first.
      • The shy fish — if one species hides constantly, stops eating, or shows clamped fins, the mix is stressing it, regardless of what the verdict says.
      • Just before lights-on and after lights-out — chasing and bullying often happen at the edges of the day when you are not looking. A quick check then tells you a lot.
      • Have a plan B — a divider, a spare cycled tank, or a way to rehome. The keepers who avoid disasters are the ones ready to separate fish at the first real sign of trouble.
      • Watch for one fish repeatedly chasing or cornering another; Betta (Siamese Fighting Fish) can claim territory, so broken sightlines and a few extra hiding spots take the heat out of it.
