Yup... the nice thing about soft corals is that your water doesnt have to be perfect and you wont need to dose cal/mag but lps may need dosing ... sps fed will need dosing and a clean high light high flow environment for the most part
In a tank that size idk what you'd consider noticeable lol ... you could grab a few varieties and make a zoa garden or buy a colony but I like watching them grow. ... it really depends on the zoa/the conditions they are in.... could be a couple new polyps per month or a couple per few months
I would which a lot do get several zoa drags and put them on a rock section with spacing between and let them grow out over that whole rock which is referred to as a zoa garden.... generally zoas are a little smaller and palys are a little bigger then them and you can generally mix and match between them to create said garden
If it is definitely ich I would put all your fish in an appropriate sized quarantine and treat with copper preferably cupramine. Monitor those levels daily to insure it's done right and leave your tank fallow (fishless) for at lease 60 days to let it die off in there as well.... do not use medicine in the display as most inverabrites and coral can't tolerate it. And I would from now on always quarantine fish before adding them to your display I hope this helps!
Yes and some people treat fish that are known to be more prone to certain things regardless of if it is apparent that they have it or not.... also treating something once it's in the display sucks and it's easier to treat 1 new fish then all your fish if you have many plus having to catch them. And you usually cannot treat something in the display without killing other things with the treatment. Like copper will kill inverts. Usually 30 days is enough for something to become apparent and if you treat something its 30 days of health on top of however long the treatment was
I don't have fish lol ... I personally wouldn't just cuz it would be too effort for my style of reefing. ... copper treats all sorts of things so if I did I would probably use that and a food with dewormer in it but idk.... I would probably quarantine and monitor the every new fish that comes in for 30 to 60 days at least. If something seems a miss pinpoint it then treat them.
If I were you I would pick up mr saltwater tank's guide to quarantine and fish disease. It really answers any questions you'll have on this topic and is easy to navigate and read and doesnt go all confusing with too much technical talk.
Yeah I just have such a small tank that I may get a go by eventually but they jump and I don't want a screen top lol so I have sexy shrimp and a pistol shrimp instead XD
