Tips for Taking Care of Glowlight Tetras and Their Tank Mates

Ideal Living Conditions (Aquarium Maintenance)

Your most important role as a fish keeper is to have an immaculately maintained tank. If you are considering getting different types of tank mates for your Glowlight Tetras, noting whether they are schooling fish or not is of utmost importance.

Although you may be excited to add new fish to your tank, it is necessary to know whether any adjustments need to be made before you do so. For this, you can always consult with the seller or breeder of the fish to figure out what type of water conditions they require!

Finally, although most of the fish in the list above require an abundance of live plants as this will imitate their natural habitats, make sure not to overdo the plantation. Since most of these fish are schooling fish, they will need their space to swim around freely in their groups too.
