Bleeding Blue Tetra (Hyphessobrycon margitae)

Remarks: The Bleeding Blue Tetra (Hyphessobrycon margitae) is a fairly new tetra, only being officially described in the late 2010's. These fish were formerly sold under the trade name H. sp.

Males, more so than females, have bright red at the base of their unpaired fins, as if the fins were bleeding. These fish are very active swimmers and will appreciate tannin stained water, but it is not a requirement. They stay fairly average-sized for most community standards and can be kept with a variety of small to medium fish, such as dwarf cichlids and various tetras.  In order to fully enjoy their beauty, we recommend keeping a group of 10+, which will easily fit in a ten gallon tank or larger.
