Unhappy nem
I would love some help with my nem. Its a green bubble tip, and I've had it in my 65 gallon tank for about 7 months. It is surviving, but certainly not thriving. Here are the details of my setup:
Lighting: 36" Current USA Marine Orbit LED fixture, sitting on its legs on the top of the tank (approx 2" above surface of water) White lights on from 9a-5p at 65% Blue lights on from 7a-7p at 80%, and from 7p-10p at 20% My water chemistry stays pretty consistent around (according to an API master test kit that has, admittedly, expired): PH 8.0 Ammonia 0 Nitrite 0 Nitrate 10 Kh 9 Calcium 400-420 Phospate 0 I don't know if it is related, but I am battling hair algae in my tank. I know that means I probably have masked nitrate and phospate, but my RO/DI tests clean, I'm doing regular water changes and vacuuming out as much of the algae as I can. A photo of the tank, and a close up of the nem are attached. The nem is located halfway up the tallest rock, which leans against the back of the tank. |

Is it shrinking? It looks very small.

It is quite small. Perhaps 1.5" across and 2" tall? It was much larger when I purchased it, but it has never been very happy in my tank and has stayed small. Sometimes the fronds extend a bit further, but never like you'd expect from a nem.

I am not familiar with your light but light is one of the most common causes for unhappy Nems. In a 65, you need to be pushing 165w min, say 200-300 ish PAR
Also, yes from the pic, you likely have a bit to much phosphate (lower this with GFO or LC) and nitrate a bit high (maybe dose NoPox) better at 2-5ppm in a mixed reef. The nem uses light for its phosynthetic process creating sugars and amino acids for metabolic growth. You don't mention feeding, this is beneficial once a week, just a squirt if Mysis if brine is fine. Also make sure your salinity stays at 1.025-1.026, and temp 76-79, both these very important. Maybe some of this will help you. Last edited by Uncle99; 12/29/2018 at 09:24 PM. |
