How do I plant my cryptocoryne?
Cryptocoryne plants, also known as “crypts” for short, are a kind of rosette plant that requires substrate and needs root tabs to grow well. Common types include Cryptocoryne wendtii, Cryptocoryne spiralis, and many other species. Similar to sword plants, you want to bury their roots while keeping the crown of the plant above ground. Crypts are very prone to melting whenever they’re introduced into a new aquarium, so don’t throw away your crypt if its emersed leaves fall off. Once the plant gets used to its new surroundings, submersed leaves will soon appear. Before...

How do I plant my anubias, java fern, or other rhizome plant?
The most popular types of rhizome plants include anubias, java fern, and bolbitis. They all have a rhizome, which is like a thick, horizontal stem or trunk. All the leaves and stems grow upwards out of the rhizome, while the roots grow downwards from the rhizome. The great thing about rhizome plants is that you don’t need any substrate to grow them. You can wedge them between cracks in rocks or mount them to driftwood using super glue gel or sewing thread. (For more details on how to use super glue gel...

How do I plant my Amazon sword or other type of sword plant?
Swords are classified as a rosette plant, which means all the leaves grow out of the base of the plant in a circular pattern. Examples include the Amazon sword, red flame sword, and dwarf chain sword. Many sword plants grow very tall, so make sure to plant them in the midground or background of the aquarium so they won’t block your view of other plants. Use your fingers to dig a hole in the substrate and bury the roots of the sword, or you can use planting tweezers to push the plant roots into...

Can I use the Quarantine Meds Trio all at the same time?
Yes, the trio of quarantine medications (which contains Maracyn antibiotic, ParaCleanse antifungal, and Ich-X anti-parasitic medicines) can all be used at the same time. We have thoroughly tested this combination on thousands of fish that we bring into our retail store.

If you bought an air pump from the pet store, most likely it’s a diaphragm air pump, which uses a diaphragm that rapidly vibrates back and forth to suck in air from its surroundings and then push that air into your fish tank. This vibration unfortunately can become quite noisy over time. Try these solutions to make it quieter: Place a small towel, block of foam, or other soft material under the air pump to cushion the vibrations. Make sure the air pump (and its cushion) is resting on a...
