I put my pacu (fake looking pirranah) and 1 tiger barb and swordfish in
my pond and 5 brown clawed frogs after a fish tank leak. After 2 weeks
the frogs doubled in size the tiger barb is fine the swords are ok and
the pacu are huge. I had put (2) 500 watt heaters in and the water is
about 72-74 The heaters help a lot otherwise the water goes to 62 at
night. Can I keep them in the pond all summer? They seem to love it and
the turtle dont catch them. The pond is about 300 gallons. Thank you
