If you were to recommend coral to a beginner what would it be?
what livestock would you recommend for a beginner?
If I were going to get a anemone what would I get?
why do we use carbon for in our fish tanks?
I got new clownfish which are domino clowns and they are laying on the bottom on the sand bed still moving don’t know what to do?
1st coral - Softie - Leather, zoa, toadstool or stuff like that. Great way to start and watch something grow. Beyond those, you'll start looking at the stony coral, LPS and SPS.
SPS - Montipora, pocillopora, bird's nest (seriatopora).
LPS - Favia, Candy cane (caulastrea), duncan.
Everything listed above is pretty hardy and readily available. Start with a softie or two and go from there.
I have a few favorite fish but for your tank, I would seriously consider a yellow coris wrasse. They're hardy, have a great personality and are brilliantly colored. As long as you have a complete and tight lid, they are one of my favorites. However, the do jump out of the tank (carpet surf) a lot, seriously, all the time. I'd be willing the bet that they are the most common fish that end up as "fish jerky" if you don't have a good lid. They're such a great fish to keep that they'd be $$$$$$ if they weren't so easy to come by. Caveat: I would say most of the same stuff about the Royal Gramma and that's another one to consider.
Rock Flower anemone's are awesome and come in all kinds of crazy colors. Clown don't typically "host" in them but they're a great into to keeping anemones.
Carbon absorbs a lot of toxins. Carbon itself is very porous and will absorb a lot of "organics" as well as any metals, chemicals or other contaminants that can get in our tanks. Rather than go down a rabbit hole, check out this link:
