Thanks for the feedback. I guess the roots at the front are normal and so won't worry about these. And we did trim the dwarf grass to an inch in height so hopefully this will facilitate spreading; we will do this on a regular basis. I'm posting a few pics of the newly timmed grass - the brown patches are more visible now, but this is apparently normal as well so it's just a waiting game with respect to the spreading. I did receive some feedback on another forum that indicated our fish selection wasn't the best for this type of tank, which was a little surprising. The person who did our tank works at a well-known fish store in NYC, and we dicussed the choices with staff and owners there. From what I've heard from others, the plecos are known for nibbling on driftwood and moss, so we should remove them if we want the moss to cover the wood. I was also told that the loaches and known for digging so this would prohibit the spreading of the dwarf grass. And finally, another poster said the SAE would become more aggressive later which could cause problems with the Discus when we add them to the tank. So, it would seem only one of the four varieties we currently have (the Ottocinclus) are appropriate for an Amano tank. At this point I guess we're going to remove the SAE, loaches and plecos, and add the Discus. At that point our tank would have only ottocinclus and discus. Does this sound like the best way to proceed? I would appreciate any additional info with respect to fish, and what is and is not appropriate for an Amano tank.
