Care Guide for Chili Rasboras — Spicy Red Nano Fish for Planted Tanks If you are thinking of setting up a nano tank with live aquarium plants, then you have to try chili rasboras or mosquito rasboras.

However, they often get passed over because the juveniles sold at pet stores are miniscule and look washed-out. Find out what it takes to raise these stunning nano fish so they reach their full adult coloration ...

How to Balance Aquarium Lighting to Grow Healthy Plants (and Avoid Algae) A brand-new planted tank always looks so beautiful and pristine, but if the tank is unbalanced, those same plants may become sickly-looking and overrun with algae within a couple of months. Plants and algae both use the same resources— such as light, nutrients, and carbon dioxide — so the goal is to balance these resources so that the plants grow stronger and outcompete the algae. For instance, too much or too little light can cause algae growth, so we need to fine-tune it for optimal plant g...

How to Treat Camallanus Red Worms in Aquarium Fish Fish diseases can be notoriously hard to diagnose, but one of the more easily recognizable illnesses is an internal parasite called the camallanus red worm. There are multiple species of nematodes or roundworms that are part of the Camallanus genus that can infect aquarium fish.

However, added stress factors like bad water quality or tank aggression may weaken the immune system, allowing the...

Top 10 Aquarium Plants for Breeding Fish and Raising Fry If you plan on breeding fish and want to increase the survival rate and growth of the babies, we love using live aquarium plants. Not only are they beautiful to look at, but the foliage serves as spawning sites for the parents to lay their eggs. Once the newborns hatch, they need constant feedings to keep their small stomachs full, and the plants help cultivate the growth of microfauna that the fry can graze on. They also purify the water by absorbing the toxic waste chemicals produced by the...

How to Drill a Hole in a Glass Aquarium the Easy Way While most fish keepers start off with easy, off-the-shelf filters from the pet store, some hobbyists want to take their aquarium filtration to the next level. By drilling a hole near the top of a fish tank and adding a bulkhead (i.e., waterproof plastic fitting that prevents the hole from leaking), aquarium water can be directly plumbed out of the tank and into a custom filtration system — like an aquarium sump, canister filter, or automatic water change system. Everyone has a slightly diffe...
