Subwassertang Is a slow-growing liverwort aquarium plant and is hands down my absolute favorite plant in a shrimp tank setup as it provides lots of cover for small shrimp and berried females looking for a place to have their young, it also grows very large and a vivid bright green color with a broad surfaced congealed leaf structure for your shrimp to graze over.
Other Common Names: Süsswassertang, Süßwassertang, Round Pellia, False Round Pellia.
This plant will eventually grow into a maze for your shrimp to play and hide in, it also does very well in soft acidic water conditions which suit our bee shrimp, Subwassertang also prefers a cooler temperature around 20-23c which is perfect for shrimp, in harder water conditions this plant is prone to algae infestations and can melt away to nothing. If your plant starts to brown then you must look at your temperatures and correct any issues.
Subwassertang while slow growing can reach around 10-15cm a year in diameter and it does very well free-floating or attached to things like driftwood or rocks, it can also self-attach itself to things like glass in your aquariums so think of the growth of this plant like a spreading bacteria in a culture plate, I use thread or very thin fishing line to lightly bind subwassertang to an object I have also tried to use superglue to attach subwassertang to things but the plant really didn’t like it at all, the broad leaves would turn white and eventually break away from the item, also when this plant gets very large it can rot near the center causing it to detach itself but this is very easy to fix.
Lighting and Ferts:
Subwassertang likes a medium to low light tank but can do very well in a hi-tech tank providing you can give it stable Co2 concentrations and traces of fertilizer.
It also seems to really appreciate me adding extra montmorillonite clay into the aquarium and is visibly greener a week after dosing.
This plant reproduces by division, you can break off small pieces of subwassertang and it will grow a whole new plant. This plant should also not be planted into the substrate or it will die.
Subwassertang also wrongly gets called Round Pellia which is a different species of plant altogether.
For ideas on what to do with your subwassertang see my videos below, you can also make Subwassertang ropes to hang in your aquariums which look very attractive once they fill in or you can attach it to things like driftwood, it will also attaches to things like a rock. Subwassertang also likes a medium flow rate in a tank. The Subwassertang I sell might also contain the odd piece of duckweed and it might also have snails in it but I do try my best to remove all visible things that shouldn’t be there if you want 100% pest free plants you need to buy invitro plants and not from me.
