Here's my 29 gallon, this will pretty much be a grow out tank but I'll always keep a few little cichlids in here as placeholders for some nice viewing in the bedroom.
The first picture is from today when I added a bunch of rock and then second is to show you one of the more complex spots that they really seem to like. I plan on building up the left side (your left) a bit more and making it all a bit more connected over time. This summer there will be a ton of rocks in there, but there will also have to be some different fish as those 4 fish will probably be too big for the 29 and will need to be moved to the 55.
Thanks for looking!
