Cryptocoryne Beckettii Petchii rooted on Lava Stone can be placed straight into the aquarium to provide a perfect instant effect. Cryptocoryne Beckettii Petchii is a small variety of Cryptocoryne Beckettii from Sri Lanka, which has beautiful, slightly fluted leaf margins, 10-15cm long. Leaves become dark olive-brown with violet undersides. Like many other Cryptocorynes, the leaf colour and shape depends largely on environmental conditions in the aquarium. Tropica Plants On Wood, Lava Stone Or Coconut ShellIntroducing the Tropica AquaDecor range of live aquarium features. Plants are pre-grown directly onto wood, lava stone or coconut shells to provide instant depth and perspective to your aquarium. Hardier than plants grown in pots, the AquaDecor range of products can be used in a variety of applications, allowing you to create an aquarium that looks mature from the very beginning. Plants pre-grown on wood, lava stone or coconut shells can simply be positioned where desired in the aquarium to create an instant feature or focal point, whilst simultaneously offering an excellent hide-away for shy fish. For aquariums with fish that are hard on plants both Microsorum and Anubias are recommended.
