Kind of hard to tell.. that last pic was a few days ago but if I had to guesstimate I'd say around 5 inches
My fish is the same, doesn't like bright environement. However, you can try putting a slightly bigger parrot fish and a pleco. It might help.Hes been pretty skittish and acting a bit strange. Doesnt like the light at all now. Goes and tries to hide when the lights come on, it might be the jdl, some others experienced skittish fish but idk
