Andy, dolphin shots are in the private collection
Neal, thanks for the comments. I don't know if I really have any advice. It took me about 9 months to get that tank looking like that, and I think it's where I want it now. We started out with fake plants, the center tall piece of wood, and the caves on the right side of the tank. A lot later, probably six months, we ditched the fake plants and went all live plants. Then we upgraded the light, and went through a couple plants until we found this combination. We also dealt with a lot of algae (which shrimp have taken care of). All that to say it's all personal preference. My goal was to NOT look crowded, so I do appreciate your comments. As impressive as the heavily planted tanks are, I think I prefer a more minimalist approach. As for tips or advice, I think first I'd say take it slow. You could get one plant that grows into enough for a big space (like our onion plant). Second, I'd say leave some good swimming space, and some good open sand/gravel space. Finally, make it your own. I see tanks all the time that I think look cooler than mine, but I've tried, and I just can't recreate them. I finally stopped trying and ended up with the tank you see here. Personally, it's the perfect balance for me and I wouldn't change anything. You asked a simple question and got a lot you probably don't care about, but hopefully something in this long rambling mess will help you
Also, Figure 8 puffers are brackish. They can be kept in freshwater (the live in freshwater in the wild), but for some reason their lifespan is MUCH shorter in freshwater in captivity, so it'd be best to stick with brackish.
