-In this episode we postulated that Apistogramma panduro could be considered a coolwater Apisto. This depends on the criteria of “coolwater”. Apistogramma panduro can go down to 20°C/72°F. In the context of the conversation in this podcast episode, Apistogramma borelli would have been a better example, as they can go down to 18°C/65°F.

  1. Hello 🙂

    I’m returning to the aquarium hobby and i’ve really been enjoying your podcasts!

    If I may ask could you do an episode on Lake Tangyaika prehabs or maybe an episode on cool/pretty stocking ideas for aquariums?

    Keep up the good work!

    1. Maybe focused on Medium/bigger aquariums. Like lets say 60 Gallons

    2. We’re planning on doing a Lake Tanganyika episode someday.
