My tank is acrylic so i drilled two inch holes on the roof to fit the cuttings through. The roots grow from there and flow right into the water. I don’t have any issues with the anubias having any noticeable nutrient deficiency.Interesting. Pothos has similar leaf shape as Anubia barteri, and can fool people into believing they are the same plant. How do you secure the pothos onto the wood shelf? Do you find the pothos grow too fast and steal nutrients from Anubias.
Do you have an open top tank or partially covered to prevent PB from jumping out. PB are game fish and good jumper. An angler told me he caught PB in Amazon in 5 lb range with record 25 lb, and I assume it is different species from yours.
The tank is covered so haven’t had issues with the bass. I would say my kels are probably 3-4 lbs easy if not larger. The intermedia will get to 24” over time woth then being about 16-18” now. They should probably get close to the 5 lb range.
