Aquarium Update 9

I have not done much with the aquarium recently. The algae are under control after reducing light levels and times. The Chrysymenia weed is growing everywhere and not looking too pretty. I will have to replace some rocks to get rid of them. My only fish is a Common goby Pomatoschistus microps, who eats bits of shrimp out of my hand. It also attacks Grey topshells when it is hungry. I would like to have have some Goldsinny wrasse and Mullet as they are beautiful and do not seem to fall prey to the Snakelocks anemones, but these species are difficult to catch. I will collect a couple of squat lobsters as they are very entertaining to watch. Ideally Spiny squat lobster Galathea strigosa, as they are among the most nicely coloured animals to be found here. They are not common in the intertidal, although they might be common subtidally (I noticed one in a picture I took of some Bispira volutacornis worms recently). The Goby with a full belly:IMG_5775So for now just a little inventory. Molluscs: Turban- Grey- and Purple topshells, a Sting winkle, Thicklipped- and Reticulated whelks and assorted Periwinkles. Crustaceans: Common prawns and Hermit crabs. Anemones: Beadlet-, Strawberry-, Plumose- and Snakelock anemones and a Red Speckled Anemone. Echinoderms: one Sea urchin, a bunch of Cushion stars, the odd Brittlestar and a nice Seven-armed starfish Luidia ciliaris that I recently found in a rock pool on Castle Beach. This species can grow up to 60 cms and hunts for other echinoderms, let’s see what happens!IMG_5735

Aquarium Update 8

Another long time without a post. A lot has happened to the aquarium and some of what I post here is already outdated, but here goes. My Daisy anemone has buried itself and has not resurfaced but the Red-speckled anemone is growing well. I found the Dahlia anemone I was looking for, but lately it has been pestered by a Purple top shell, which has left a scar on its column, I hope it survives. The most dramatic event was that the Snakelocks anemone managed to kill my Sea scorpion (but not eat it, it was too large). This must have happened when I  removed some of the rocks, startling it and make it swim in the wrong direction:IMG_4963Poor thing (although it had eaten 22 of my mullet so it works both ways I guess…). The good thing was that I could try keeping some other fish again. Using my net, I caught some Two-spotted gobies as well as a Common goby Pomatoschistus microps (I think, there are some very similar species) and a Goldsinny wrasse Ctenolabrus rupestris. The total tally from netting off the Flushing quay is now eleven fish species, not bad. The Goldsinny swims around the tank a lot and does some digging; it seems to be a more interesting fish to watch than the Corkwing:

The Plumose anemones Metridium senile are strange, they can be all shrivelled up for days, be short and squat or all extended. Here three pics of the same individual:Presentation1The Turban top shells Gibbula magus are very nice to watch (the Grey topshell Gibbula cinerarea gives a sense of scale). I found a Sea urchin Psammechinus miliaris and decided to try it out. It spends half its time under the gravel and pops up here and there with shells and pebbles attached to it. Let’s see what it does! Lastly a picture of the tank. I had attached a young Sugar kelp Saccharina latissima to the tunze pump with an elastic band and now it has attached itself to the plastic.IMG_5091
