This looks light long tentacle anemone which isnt too picky with lighting but assure light offers spectrums of blue , white and UV
They do best in tanks that have been running for at least 4 months as they dont fare well with changing chemistry and spikes. Monitor water regularly to assure there are no major changes. Ammonia and nitrate levels should be safe verified by using a good quality test kit and Not API either.
Here are some water parameters to follow.
- Water temp: 77°F - 80°F (stay close to the middle of this range)
- pH level: 8.1 to 8.3
- Alk: 8 to 11 dKH
- Salinity: 1.024 to 1.025
- Nitrate < 5 -10
- Phosphate < .04 - .06
Anemone lighting is important as part of their care as they need good light as they are photosynthetic which means that they absorb light to produce their inner food and growth. Anemones have zooxanthellae in their body which they feed on. Without proper lighting, your nem will expel its zooxanthellae which looks like it is poop and then bleach out which often leads to death.
Moderate flow is recommended as well as moderate light. Too much flow will cause the anemone to stretch out and look stringy and too little flow will cause them to climb. Avoid direct water flow directly at the anemone which stresses them out and again assure light is moderate and flow is not excessive in your case
Ai Hydra 26 or 32 OR . . . 2-3 orphek OR3 bars will take care of lighting needs
