Before ripping into how bad this tank is going to look please refer to this thread: https://www.fishlore.com/fishforum/saltwater-beginners/228420-craigslist-saltwater-setup-help.html It gives an outline of where this tank came from. Stats: 20g long glass aquarium ? lbs of live rock Plain old aquarium sand Hydor Koralia nano 240+425 Aqueon 10 HOB filter Finnex Fugeray light Fluval M heater Stock: (still learning what some of these are) Yellowtail Damsel Clownfish varient? Chromis Scooter blenny Sand sifting star Skunk cleaner shrimp Urchin that i believe is a pencil urchin Emerald crab Red leg hermit (I think, it has red legs) I think I've seen another hermit also Snails that have long trunks that bury themselves and leave the trunk sticking above the sand Some kind of round shell snail that i have to keep flipping back over when i find it on its back Plans for future: Add more live rock, possibly add more sand but not sure yet. Remove the HOB once i get more live rock, I'm don't want to remove it in case there is a lot of BB in the filter and cause the tank to crash. Maybe just maybe build an overflow box or system and make a 10g sump, its unlikely but maybe some day. The pictures: Can somebody confirm that on the right most rock is an apitasia, I think that's what it is, it's the only one i see anywhere in the tank. Any comments, criticism, suggestions and advice is very welcome and appreciated. Thanks for checking out my thread.
