barb fish eat algae
There are fish that are a "rosy red" colour that are livebearers. There are both Platties and Swordtails that can have such colouring. But if you are referring to a fish that is called a "Rosy Red Barb" then these are egg layers.
Depends on what he looks like, or does. Maybe something that has to do with fire, orange, or if he's fast bolt, lightning.
The turtle will likely eat the rosy barbs if they are small enough.
the rosy red fish is the boy.
If by "Rosy Red" you mean a Rosy Barb they can live for 4 years or so. If they are used as a 'feeder fish" their life span obviously would only last as long as they are not fed to something.
A 4 gallon fish bowl is not adequate for these fish and you were miss-sold them. Is this bowl filtered? If it's not, it's not suitable for any fish. A 4g, filtered and heated, is only really suitable for a single Betta or a dwarf shrimp tank. In reality both these species of fish should be in shoals of their own kind. The Rosy Barb should be kept in a group no less than 5, the Tiger Barb no less than 8! For a shoal of Rosy Barbs you need at least a 15-20 gallon, for the larger Tigers, no less than 30 gallons. Return these fish to the store and do more species research!
I wouldn't; rosy red minnows are usually full of parasites.
The male Rosy Barb has a black tip to his dorsal fin the female does not. In breeding condition the male is much more rosy than the female. Males are know to have dark areas under them. Plus they are much more pretty than females. Usually males look like females and females look like males.
A rosy red is a color that is a shade of pink with a slightly reddish tint, giving it a soft and warm appearance. It is often described as a delicate and romantic hue.
the fish will have dots
Male rosy red fish tend to have brighter colors, especially during breeding season, and can develop small white tubercles on their head. Female rosy red fish are usually larger and have more rounded bodies. Additionally, a trained eye can differentiate between the genital papilla of males and females, which is located near the fish's vent.
