That carpet is incredible! Love the tank. Understand you want change. Would you simply reduce plant species and change the rock placement for the Iwagumi style? Would this make tank maintenance a lot easier or no? If you have shrimp in there doing well you could add some small schoolers to enjoy right? I look at those pictures and see myself watching the tank like I do my own and it just seems fish add so much, but I understand if it's not your thing. Perhaps your dosing/CO2 would bother them? I do not have CO2 in any tanks. However, seeing the results of this carpet and several other impressive tanks on this forum have me planning for a high tech tank in the future. Enjoyed reading this thread, my high tech/plant knowledge is growing... as is my kung pow humor.
