Clown Care: as an FYI , I keep my salinity around 1.020 to 1.022 (but up to 1.026 should be fine) and have been feeding the clowns a combination of the following a few times a day: Cobalt Mysis Spirulina flakes, shrimp and/or scallops that I blend in a blender to a small pellet size, TDO Chromo Boost (size Small or extra small) – if desired you can order TDO from Bulk Reef Supply or you may be able to get at a local pet shop. A 3 oz package should last 3-4 months for 2 clowns.
Nem splitting: Anemone is around baseball size rainbow bubbletip. These rainbows are extremely prolific and split often. I started with one around 3 years ago and now have several hundred. I also have roses and green bubble tips, but they do not split at all as often. One reason is that the rainbows do not normally get much larger than baseball size before they split, where as roses and greens will grow to around basketball size. No way to tell results others may have, but for me these rainbows are extremely prolific.
Nem looks: Coloration is very dependent on lighting. Also the bubbling and sparkle (some nems have white little dots that seem to sparkle on the right light – like my rainbow nems). The degree of sparlke and bubbling will also depend on lighting and overall tank conditions. I have multiple tanks that I try and keep very much the same as far as water quality/composition, temp, and flow, but in some tanks the nems bubble and sparkle more than others.
Nem Care: Anemones need an established tank to live and thrive – I would suggest at least 6 months (unless tank was started with live rock/sand/etc. so that it is really not a”new” tank. Also good to feed a small piece of shrimp (small Lima bean size) once or twice a week to help with growth and overall health. I keep temp around 78 degrees Fahrenheit, with a medium water flow – nems need flow. Also be sure to keep water quality high, with keeping nitrates as low as possible. Otherwise these nems are extremely hardy and should split often and have an ongoing life.
