Parkinson's Rainbowfish Tank Setup
Plan for at least 40 US gal min of water—that is the minimum in our database for a workable setup, not a challenge to crowd fish. Aim to hold 75–82°F and pH 6.5–8 without daily drama. These fish use the Mid-top zone most, so put wood, plants, or open water there accordingly.
What Do Parkinson's Rainbowfishs Eat?
We record diet as Omnivore. Offer a few food types that match—dry, frozen, or gel—and swap now and then. One flake every day for a year is how dull color and gut trouble creep in.
