Hi,
I am a newbie (after a lapse of 20 years) and have regularly noticed, ok my darling wife has, that the fish we have every couple of days get very excited and feed at the top 2-4 inches (50-100mm for the metrics) of the tank and she asks me why.
I have't a clue so I thought I would ask around.
Details of the system.
Tank/Sump 9 months old. 50 Gall/ 18 Gall (200l/68l)
Nitrite 0, Nitrate 5, Phos below 0.03, Alkalinity 9, Cal 430, Mag 1560 (early days so this is a bit up and down as no SPS). Sal 35ppt, Temp 24.8.
Sump has a refuge with Calerp growing well and reg harvested, various critters, small brittle stars, pods (new added every month), shrimps and small snails.
I feed the sump 2 ml of Concentrated Phyto a day and general TMC frozen food in small quantities to the main display tank 3/4 times a day to help the Anthia's out mainly.
We have 3 Evansi Anthia's, 2 Silver Belly Wrasse, 1 Tailspot Blenny and 2 Common Clowns plus various corals (softies and LPS so far) and inverts. No SPS as scared .
Every now and again (around 6-7 O'clock in the evening) the 2 Silver Belly Wrasse start the process of by circular swimming about two inches from the surface, mid tank. The Anthia's swim underneath expectantly. The wrasse will break the surface and disturb it and then it's a feeding frenzy by all. All we have done is sit on the sofa.
Any idea's much appreciated so I can give my darling wife an educated answer.
Very nervous as this is my first post.
Thanks
