. Other such corals like the frogspawn would be octospawns, hammers and torches off the top of my head! As for equipment... water changes would do perfect but maybe an led light would be enough and a small hang on back filter for flow and overall filtration. Go on tidal gardens website and they give great info for overall care and almost everything with each coral specimen What's the needs in terms of ph, salinity, and other stuff for the frogspawn?Look for soft corals as a beginner since they are more hardie when first starting out. Then you can move onto the LPS (large polyp stonies) you're wanting
This sort of advice is posted a lot and while its good advice and well intentioned I cant help hut disagree whenever I see it. If you get a bunch of softier and brown corals just to start out well, thats gonna fill a 10 gallon to the brim in no time. However some good soft corals to start with that you wont regret filling your tank with are zoas and palys, rhodactis and discosoma mushrooms (real hot right now!). And honestly maybe a few years ago when thr hobby was harder to get into it made sense to aboid stony corals as a beginner but to be honest I wpuld cosider most LPS beginner corals nowadays as long as a tank os set up well. Good LPS that are easy to keep are acans. Very easy to keep and add great color to a tank. Another coral family thats great is Euphyllia. Thos includes frogspwan which I see you already have your eye on, and I recommend getting a golden torch coral. Its a classic really the colors are just unmatched and theyre so easy to come by I wouldnt stock a tank without one. Oh and #Welcome to R2R!Look for soft corals as a beginner since they are more hardie when first starting out. Then you can move onto the LPS (large polyp stonies) you're wanting
