I have never had a problem with my jungle Val, so super hardy and healthy. I have to hair cut it all the time or it gets over a metre long. No fertiliser or anything. I have ambulia in there but you can’t see it as my Val is taking over lolWow it is really doing good, I gave up on jungle val between the mystery snails eating it and it melting or just breaking up and floating away. I would clear the area between the front glass and the sunken boat in the middle.
Nice tank there, although I would ditch the fake stuff and get more bog wood in there with a nice big shoal of tetras, stunning.
