When choosing the right food for a Danio rerio colony there are a number of factors to consider. This guide will help navigate the roadblocks of live food selection. These challenges are split into two main categories: First level factors and second level factors. In this article we go into more depth on each food type and considerations you should take into account when deciding which food is best for your zebrafish.

Maintaining water quality is crucial for successful zebrafish maintenance and husbandry, especially during the startup of a fish rack. This video discusses how to keep track of the water quality parameters (ammonia, nitrites, nitrates, and pH), gives an example of how we started our fish rack, and the process of the nitrogen cycle for initial rack set-up.
This video discusses the daily maintenance and upkeep of zebrafish, including keeping track of population health, our daily zebrafish rack checklist (water flow, buffer fills, etc.), and the fishes’ feeding schedule.
An important, but time-consuming, aspect of zebrafish maintenance and husbandry is the proper cleaning and disinfecting of lab equipment. Tanks should be cleaned every 5-6 weeks — this video walks you through the handling of zebrafish during tank to tank transfers, and the cleaning of the old tank.
In an effort to create better research models for epilepsy, we’ve been working on a grant-funded project to humanize numerous C. elegans genes. Learn more about our progress and our findings in this blog.
How can you better study your gene of interest? Fluorescent tagging! This video showcases InVivo Biosystems’ fluorescent screening process using zebrafish. Watch the video for example photos of embryos that have fluorescent markers.
