Neons often spawn in the morning. While spawning, neons will chase each other through any plants. While all the neons may spawn in one day, the actual act is done between a pair. The male and female intertwine, and the female may become vertical. Each female produces 60 to 130 eggs all over the plants and ground. The eggs are not sticky. The parents should be removed so they do not eat the eggs. The eggs are light sensitive so keep the developing eggs out of direct light. Eggs are prone to fungus especially in light (for more information on egg fungus, check out my fish health page. The eggs hatch in about a day. After the fry are free-swimming in about four to five days, they can be fed strained egg yolk, infusuria, other microscopic live foods, or Liquifry (which is mostly yolk). Provide subtle lighting over the tank once the fry are swimming so they can see their food. Often, some fry will not survive.
