this is what's was in my tank, the fishes will work with WAL, But no Garantee. I lost about 1300 dollar on my WAL, just to try which fishes work.
Also Pleco will work, they are to hard to crack. But my WAL killed a 45 cm long pleco by trapping it under a piece of wood. The WAL layed on it and the pleco died.
Well i bought a 3-4 inch clown knife, things were fine except the clown seemed very stressed by the Lung, after not eating and trying to find out why I removed the clown, the Lung is doing great getting thick and very active.
The bushy nose pleco I have in the tank is thriving on all the algae. (Tank receives direct sunlight every morning)
