Interesting developments. On Saturday the managuensis
pair appeared with the fry (2,000 of them) and drove the zaliosus
away from their spot. These subsequently disappeared behind the bogwood with their offspring. They are still there.
Then on Sunday the managuensis
ventured far to the right and apparantly met with the chancho
pair. I know that because the chancho
pair suddenly had many more fry to tend for. Then managuensis
must have retreated; they are back in the left hand corner.
Today the situation is about the same, although the chancho
pair has either lost or eaten the foreign fry.
And you know what? All this is happening without any damage to the fish. If I weren't already, this would surely convince me of the advantage of large tanks (for big fish anyway).
