Tips for growing bulbs and our bulb warranty: (Applies to ALL Aquarium Plant Bulbs: ie: Dwarf Lily, Aponogeton, Barclaya, etc.): Try placing your bulb(s) in a folded “moist” paper towel (not sopping wet), put the paper towel in a plastic bag, an air-tight bag is not necessary, folded over or stapled is just fine. Place this bag on something warm where you won’t forget about it… i.e. on top of your cable box, or your computer! Wait just a couple days and “voila!” Your bulb should have some protrusion poking out of it, this is the actual plant stem, the roots will grow much later, now you know which end is the top, this will help you not to plant your bulb upside-down! You have just pre-germinated your bulb! Another way is to just drop the bulb into your aquarium without burying it, (allow it to just sit on top of your substrate), wait for growth to appear (usually within 5 days for some, and up to 2 months for others…like Barclaya) and then push the bulb into the substrate leaving just a smidget of the bulb’s crown exposed.

WARRANTY INFO:  Our bulbs are squish and sniff tested before we ship them, however, we cannot guarantee that it will grow, if you want a guaranteed plant from a bulb, then we recommend you just buy the plant.  That bulb will already be growing when you get it.  The only reason we do not guarantee bulbs is because we cannot be at your home to make sure you have the perfect growing conditions to make your bulbs grow.  It has been our past experience that roughly 90% of the bulbs we sell will germinate.  But there is a chance they wont, hence the gamble.

Aponogeton bulbs start as a tiny green shoot.  Your aponogeton will grow for months whether or not you fertilize it, regardless of aquarium pH, and regardless of your tank temperature or substrate.

Enemies.  Most smaller Plecos will not eat Aponogetons.  Larger plecos will just naturally knock or crush the apons.  Most larger cichlids, and goldfish will just like to tear up the plants leaves and use the plants as “toys”.  Apple or Mystery snails will pulverize apons leaves.  Nerite snails will ignore the plants.

Fertilizer.  Food stored in the “bulb” will get your aponogeton off to an amazing start.  Your fish will also give off nitrogenous wastes, phosphates, and carbon dioxide that these fast-growers will inhale.  Youll get bigger and better specimens if you fertilize them on a regular basis — frequent small amounts of fertilizer work better than infrequent large doses.  One healthy aponogeton can easily fill half a 10-gallon aquarium with attractive green leaves.

Planting.  If you toss your bulb in a bare tank, it will fall to the bottom and start growing.  In a tank with gravel, it will root itself.  Most people stick their bulbs into the gravel because they want their show plants in a specific place.  Dont bury your bulb.  Just stick it in far enough to hold it in the place you want to keep it.

Light.  You cant grow plants in total darkness very well.  Give your aponogetons 12 hours of light daily.  USE A TIMER!  Aponogetons WILL grow in poor light, theyll just grow slowly.

Maintenance.  In the wild, these plants will leaf out, send up a two-to- four-foot long bloom stalk, go to seed, then die back during the dry season.  Take a look at the bloom stalk on the top.  If you want to prolong your aponogetons leaves, cut off that bloom stalk before it starts blooming.  Otherwise, your show plant will go through a couple month resting cycle.  If it goes into this phase with little stored energy, it may not return

Propagation.  If you want hundreds of baby apons, dont cut the bloom stalk.  When the tiny flowers open, brush them lightly with a sponge or a brush and act like a honey bee to fertilize them.

Natural Habitat for Discus

Discus are found in floodplain lakes and flooded forests of the lowland Amazon River basin and some of its tributaries, including the Rio Negro.  These areas experience extreme changes in water level due to seasonal flooding.  Discus tend to congregate near fallen trees, known as “galhadas”, along the shore.  They prefer quiet water, and are rarely found in areas where there is strong current or wave action.

Discus Water Requirements

Discus prefer warm, soft, acidic water.  pH should be between 6.0 and 7.0, with hardness between 1° and 4° dKH (18 to 70 ppm).  Temperature should be kept between 82° and 89° F. Water conditions for both wild and hybrid discus are the same. While captive bred discus can be kept in dechlorinated tap water  reverse osmosis or deionized water supplemented will ensure the the best conditions. Discus require pristine water quality, and depending on the filtration system being used, a weekly or bi-weekly water change of 10% to 25% is highly recommended. Don’t forget to treat tap water with conditioner before refilling your aquarium!  

Housing Requirements for Discus

Discus grow to be quite large, and full sized discus will require an aquarium of 50 gallons or larger when they reach adult size.  Tall aquariums are best, to accommodate their body shape.  Current should be gentle, and décor if used at all should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees.  A few floating plants can also be added to provide shaded areas and cover. Substrate should be fine to medium grade and smooth surfaced, as discus like to forage along the bottom for food.

Discus Behavior/Compatibility

Discus are generally calm, peaceful fish, but as cichlids they can be aggressive toward one another, especially when attempting to pair off and spawn.  Shy or submissive fish should be removed if they are unable to compete. Most serious hobbyists do not mix their discus with too many other species. However, suitable aquarium mates include cardinal tetras, neons, emperor and rummy nose tetras, as well as clown loaches and dwarf cichlids such as rams and Apistogramma species. All of these fish tolerate the high temperatures and low pH/hardness required by discus.  

What do Discus Eat?

In nature discus eat a considerable amount of plant material and detritus, but also forage along the bottom looking for worms and small crustaceans.  They are omnivores and will thrive on freeze dried black worms, beefheart, frozen blood worms, and a variety of pellet and flake food. Frozen and live foods may be fed as treats or to help induce spawning.  For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.

Discus Breeding Level – Difficult

Captive bred discus will pair up and spawn relatively easily, but young, inexperienced parents may eat their eggs the first few times, particularly if other fish are present.  After hatching the young feed on heavy body mucus secreted by the parents for a few days until they begin to free-swim.  Parents will transfer the young back and forth several times a day.
