This is how Alejandro's tank is at the moment. I am trying to go more "natural" however I didn't realize the Amazonia substrate I ordered has to be cycled. . so he is without real substrate except for some rocks right now. Quite honestly, he seems to be very happy just with all the floating plants and his little mopani wood he has. I had to leave his fake anemone in there because he likes it, and he likes his pvc tunnel too. But mostly, he is all about his floating mess of plants at the surface. (BTW the reason the lighting looks weird is because I have half the tank lit by a small bulb, the other side has an LED light. So half the tank looks yellowish and the other half looks more blue.
Also I used the background with water and river rocks, and for continuity I looked through my mom's old pond rocks and tried to find ones with similar colors. I wanted steel-blue-grey rocks with a couple of orangey rocks. the orange would reflect Alejandro's color but also the background happened to have some rocks that were sort of orange also.
