With 24-26cm is merely the piece of wood meant ...

... With the "treetop" so you need a few more centimeters expect it. My jungle tree is 33cm tall with the leaf crown. That is why this Medium trees will soon move into a 50cm high aquarium and for Nano basin I prefer ordering again 1-2 sapling small version.
This primeval forest trees is aufjedenfall a real highlight in the aquarium.

+ Fast delivery
+ All the leaves have a healthy green
+ The roots which were initially quite fitting to the tree, start now after 2 days already in really nice to hang loosely down
+ The leaves offer for small animals (eg shrimp offspring) hiding places
-The "treetop" extends several centimeters out of my nano tank.
