5 Easy Methods for Cooling Aquarium Water During a Heat Wave During the hot weather seasons when heat waves hit, you may struggle to keep your aquarium water cold enough for goldfish, goodeid livebearers, axolotls, and other cool water species. While it is relatively affordable to warm up the water with a heater, it can be much more expensive to buy equipment that reliably cools down the temperature. One simple tool to start with would be some kind of digital thermometer with an alarm that beeps if the water gets too hot (or cold). Then you know when i...

7 Reasons Why Your Aquarium Water Has Bubbles or Foaming Have you ever seen bubbles or foam in your aquarium water and wondered if it’s safe for your fish? Bubbles can happen for many reasons — some of them good and some of them bad — so let’s talk about what to watch out for and how to fix the problem if needed. 1. Normal Bubbles from an Air Pump Of course, the most obvious reason for bubbles is that you are using an air pump that sucks in air from outside of the aquarium, pushes it through airline tubing, and pumps it into the water. Typically, t...

How to Clean Aquarium Filters — Sponge, Hang-on-Back, Canister Filters and More Do you wish you had crystal clear water in your aquarium? One of the keys to having an amazing-looking fish tank is to make sure you regularly maintenance the filter. Aquarium filters collect debris much like a vacuum, and eventually they must be emptied out or else they no longer work as efficiently. The frequency of filter cleanings depends on how quickly it gets clogged up, the size of the filter, the bioload or stocking level of the aquarium, how much food goes into the tank, and so forth...

Aquarium Seasoning is Better Than Aquarium Cycling (and Here’s Why) Whenever someone has a fishkeeping problem and asks for help on social media or online forums, people immediately ask if the fish tank is “cycled.” Yes, it’s important to know about the aquarium nitrogen cycle, but just because a tank can process ammonia waste does not necessarily mean it’s a good environment for housing live fish and plants. For example, just because someone has an official college diploma does not mean that he or she is automatically skilled in that field. There are many, m...

Top 10 Pufferfish You Can Keep in Freshwater and Brackish Aquariums Out of all the oddball fish, we’ve always had a fascination with puffer fish because of their highly intelligent nature, helicopter-like maneuverability, and large, inquisitive eyes. Plus, they have unique defense mechanisms, such as inflating like a living water balloon and carrying the tetrodotoxin poison that discourages would-be predators. (Note to self: do not try to eat a pet puffer.) Most pufferfish are semi-aggressive to aggressive carnivores with ever-growing teeth like a beaver, so ...

Care Guide for Siamese Algae Eaters (SAE) — Housing, Food, and More If you visit our retail store or warehouse, you’ll notice that many of our plant tanks employ the services of the Siamese algae eater (SAE).

What are Siamese Algae Eaters (SAE)? Crossoch...

Top 10 Livebearer Fish to Try Breeding in Your Next Aquarium Breeding fish is one of our favorite parts of the aquarium hobby because of the immense satisfaction you get from caring for your pets and seeing them produce the next generation of offspring. Most fish lay eggs, which have a much higher likelihood of getting eaten since the eggs have no natural defenses. In contrast, livebearers (or species that give birth to live young) have a reputation for being easier to breed because the newborns are capable of swimming away and hiding from would-be pre...

Care Guide for Mystery Snails — Entertaining and Useful Scavenger Many aquarium hobbyists don’t like pest snails like bladder, ramshorn, and Malaysian trumpet snails because they can rapidly increase in population even if you only start with one. In contrast, mystery snails (Pomacea diffusa and P. bridgesii) are really cool, little pets that you can buy at your local pet or fish store for only $3–4. They cannot self-fertilize or change their sex, which makes it much easier to control their breeding, and unlike their larger apple snail relatives, they won’t ...

Care Guide for Otocinclus Catfish — Peaceful, Schooling Algae Eater If you start getting algae in your new fish tank, most major pet stores will recommend that you buy a pleco or suckermouth catfish. The problem is that most plecos grow rather large, especially the common pleco that can reach up to 2 feet (60 cm). Instead, why not get their much smaller cousin, the otocinclus catfish? They are the perfect fish that have a peaceful personality and amazing cleaning skills. Learn how to keep these adorable algae-eaters and make sure they’re getting enough to eat...
