Incorporate floating plants like Salvinia or Amazon Frogbit to create shaded areas, giving these peaceful fish a sense of security. Adding driftwood and leaf litter can introduce beneficial tannins that replicate their native wild streams.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eTank Size\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6\"\u003eDue to their diminutive dwarf size—reaching a maximum length of only 0.8 to 1.2 inches (2 to 3 cm)—a minimum tank size of \u003cb data-path-to-node=\"6\" data-index-in-node=\"122\"\u003e10 gallons\u003c\/b\u003e is highly recommended for a small school.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003eCare \u0026amp; Water Parameters\u003c\/h3\u003e\n\u003cp data-path-to-node=\"8\"\u003eCalypso Tetras are relatively hardy when introduced to a mature, biologically stable ecosystem.

Because of their defensive schooling instincts, \u003cb data-path-to-node=\"13\" data-index-in-node=\"111\"\u003ethey must be kept in groups of at least 6 to 8 individuals\u003c\/b\u003e (ideally 10 or more). In larger schools, they display tighter swimming patterns and far greater confidence. Excellent tank mates include other peaceful nano fish such as Rasboras, Pygmy Corydoras, small Loricariids, and freshwater dwarf shrimp. Avoid keeping them with large, aggressive, or predatory species that could easily view them as a snack.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"14\"\u003eBreeding\u003c\/h3\u003e\n\u003cp data-path-to-node=\"15\"\u003eBreeding \u003ci data-path-to-node=\"15\" data-index-in-node=\"9\"\u003eHyphessobrycon axelrodi\u003c\/i\u003e follows a typical egg-scattering pattern. To successfully breed them, set up a dedicated, dimly lit breeding tank filled with fine-leaved plants like Java Moss or spawning mops. Condition the parents with premium live foods. Females are slightly larger and rounder when carrying eggs, while males exhibit more intense silver coloration. Parents should be removed immediately after spawning to protect the eggs, which will hatch in about 24 to 36 hours.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePLEASE READ BEFORE ORDERING\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe photos shown on fish product pages are representations of adult fish and are NOT the actual fish that you will be receiving.\u003cspan class=\"Apple-converted-space\"\u003e \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003ePlease visit our “Ordering\/Shipping fish” page prior to checking out to familiarize yourself with our process.\u003c\/li\u003e\n\u003cli\u003eWe ship fish exclusively using overnight shipping with either FedEx or UPS.
