Feeder goldfish7/1/2023 With regular water changes and a decent filter, you should be able to keep your Rosy Red Minnows happy and healthy. It’s kind of amazing how seemingly indestructible they are, with reported survival in temperatures within the range of 32-100☏ (0-37☌). Of course, if you’re housing multiples, you’ll need more than one pot so that the males don’t fight over it.Īlthough I am listing optimal temperatures below, Rosy Red Minnows are still capable of surviving outside these parameters and are also able to tolerate varying levels of oxygen and water flow. If you get an inexpensive clay pot, turn it sideways in the aquarium and bury the bottom part of it, your Rosy Red Minnows will be happy to claim it as territory. If you’re planning on breeding your Rosy Red Minnows, you’ll need to provide them with a cave for egg scattering. Uprooting plants and changing out the substrate can really mess up the biosphere of your aquarium and put all your fish, invertebrates, and plants at risk. Pro tip: If you are adding Rosy Red Minnows to an already established tank, don’t change the substrate to accommodate the Rosy Red Minnows. If you have a bottom feeder that needs a softer substrate, go with that since the Rosy Red Minnows are so adaptable. I would choose the substrate based on the needs of your other aquarium residents. However, if you need an alternative, soft sand would also work. Finally, white or gold bars on both the dorsal fins and back of the head are male Rosy Red Minnow identifiers.įor substrate, my first choice for Rosy Red Minnows is gravel. Other differences are the darker heads of the males, as well as the fatty tubercles that grow on the males as they ready themselves for breeding. The males are about an inch longer than the females, measuring in at 2-3 inches (5-7.5 cm), while the females are 1-2 inches (2.5-5 cm) in length. One of the best ways to tell which Rosy Red Minnows are males and which are females is by looking at size. Their bodies actually resemble torpedos, a feature that allows them to swim very fast. The females have smaller bodies than the males, but both sexes have slender bodies, with round eyes that lay laterally on their flat heads. They have a solid color, but the hue gets lighter at the upper part of the fish.
