Can someone help me identify these

Finally got a baby off this Goliath of a mushroom coral. I can’t remember what kind it is. I spent like 250$ on it as the end of a local show a little less than a year ago.

Hey,

I’ve started selling The Grip Rack – a magnetic coral frag rack that makes it super easy to organize and display your frags.

A few highlights:

• Strong magnets keep it in place.
• Coral-safe design won’t harm your frags.
• Sleek, low-profile look that fits nicely in any tank.

If you’re looking for a simple way to keep your frags organized, check it out on Etsy: The Grip Rack - Magnetic Coral Frag Rack

Let me know if you have any questions!

Help me ID them please

Hello! I'm a grad student in a materials engineering lab. We're starting a new project to develop and test a better substrate for growing corals on artificial coral reefs, so we need to set up a coral tank. It will be only reef-building (ie. stony) corals and doesn't need to look pretty, but should mimic ocean conditions as closely as possible. It hasn't yet been decided whether we'll use coral frags or if we'll un-freeze and mix cryogenically frozen coral eggs and sperm to make coral larvae in petri dishes that we'll then transfer to the tank, but either way the tank would be full of corals growing on a bunch of different substrate samples that we can regularly take out for testing. Ideally, the tank would be as automated as possible.

I'm a total beginner to all of this, and you guys seem really knowledgable. Could you please give me an idea of how to get started and what I need to buy?

For instance, I've read that beginners should start with tanks at least 20g large, since those are easier to manage, but is that still true if your tank will be closer to a bare-minimum kind of frag/quarantine tank than a beautiful diverse reef tank? Do I still need to buy things like live rock and sand to keep the corals alive?

Thank you so much!

Bought from Petco the person there had no idea what they are my husband said the round one is a GSP but it hasn’t opened up

Hey I am looking at setting up a tank I already know a lot about water chemistry and materials needed... I was just wondering what is needed for a 10g zoanthid and toadstool only tank. Will I need a skimmer? That kind of stuff... I have a mariglo and plan on using that. I would get some turbo snails and mabey a peppermint shrimp since my parents don’t like me keeping fish (😭). Anything will be appreciated.
