I did a water change tonight and snapped pics of the two newest crypts added to my collection. C bullosa Bario and C yujii Sungei Nibong. This bullosa variant is the reddest bullosa next to the form collected from Sarakei.
C yujii is also a very interesting broad leaf crypt with brown veining throughout the leaf. Yujii is the first crypt i've seen with this type of veining
This bullosa patch was started with just a couple of mother plants. A nice dense patch is starting to form. They are grown in liquid rock with no fert. Just injected co2.
These plants are all submerged. Photos were taken when the water was drained during a water change.
Most (if not all) people would agree that you'll grow healthier plants with CO2, not just crypts. C bullosas are usually found in fast flowing streams. Having good water flow or currents in your tank also help distribute/diffuse the CO2 evenly. There are vitrually no dead or stagnant spots in my tank. I have two eheim canisters and two needlewheel pumps for the CO2 diffusion and I can see tiny CO2 bubbles in every corner of my tank. Even though I do not fertilize my tank, the plants do get nutrient from the water column from fish waste. I have a group of cardinals that are fed daily.
