I have found out it was a form of selliera radicans from its flowers so sorry but also Glossostigma cleistanthum has bigger leaves then glossostigma elatiniodes I think you're confused it with glossostigma diandrum with has very small leaves
Thanks I have three outside in my native tank in progress I got them to control mosquito lavae but I have bullys now so don't want them in there any more
Just an update I have added three bullies that are commens or crans their to young to tell their is also a large school of water boatmen two types and gratiola sexdenta myriophyllum pr and lilaeopsis novae zelandiae from a wild pop
The crayfish in the outside tank has been in there for mouths and it's very healhty got it when it had one claw missing now it's nearly completey grown back
