I’ve got a 40gal long, which is 4ft with 1 med fish, and about 7 smaller fish, and 1 6" catfish. I have the tank FULL of live plants and they are awesome. I’ll take pictures tomorrow, and if you wanted to stop over and check out either my salt or freshwater setups you’re more than welcome, I’m near UB south. I don’t think I’ve had a fake plant in 3 years and I never will again. There really is nothing like watching plants bloom, especially if you can get your hands on banana plants.
