I have a love/hate relationship with public aquariums: love because I am a bit aquarium-mad, and hate because quite a lot of them really are disappointing. Of course, I know all too well that it is not easy to create (and maintain) good-looking aquariums. Also, the paying public needs to be pleased and it wants to see ‘nemo’s’ and sharks which often results in the same sets of standard tanks. Although I do understand the need to educate the public, I am quite allergic to all kinds of video installations and boring props taking up space that could have been filled with tanks. I am not even talking about walkways decorated with fake polyurethane caverns or ornamental treasure chests in tanks…
I try to visit public aquariums whenever possible and from now on will review them on this blog, specifically highlighting the smaller, temperate saltwater tanks that could serve as inspiration. Last week I was in Slovenia for work and a short holiday and passed by the lovely town of Piran which has a small (about 10 large and 10 small tanks) public aquarium, all with local animals. Here is one funky looking tank housing some writhing moray eels and Grey triggerfish Balistus capriscus, the latter also present in Cornish seas:
I am not so sure about larger-sized Mediterranean Sea aquariums, as there is not a lot of potential to make them visually appealing: some rocks and the odd human implement as decoration and the fish are often not overly spectacular (see the Two-banded bream Diplodus vulgaris below). If I were to go for a large, non-planted rock tank, I would try my hand at an African Great Lake aquarium instead, with the fish being more diverse, more interesting and more beautifully colored.
One of the largest fish on display was the Leerfish Lichia Amia. It was a shame to see such a large pelagic fish in a tank with its head completely deformed due to it bumping against the glass:
I was most interested in the smaller aquariums. These housed some species that can also be found in Cornwall, such as the Tompot blenny Parablennius gattorugine and the fantastic John Dory Zeus faber (which occurs around the globe):
Some of the small aquariums were quite sweet. No seaweeds to speak of (although I saw some Ball algae Codium bursa) but lots of nice invertebrates such as sea cucumbers, clams, whelks, sponges, anemones as well as a variety of fish:
Especially amazing was the stony coral Astroides calycularis:
A Small rockfish Scorpaena notata:
All in all an interesting little visit (I had to rush a bit taking pics as the rest of the family is not as keen on ‘the mysteries of the deep’ as I am…). Lots of types of invertebrates that I would like to try to keep such as sea cucumbers, but for the moment I will focus on seaweeds. I had no time to have a proper look at the rocks outside (the Mediterranean has very small tide differences anyway) and I had not even brought my snorkel. From the glances I got, the Adriatic coast did not have much on the Cornish coast though!
The tide this Sunday in Flushing was as low as it was the day before in Mount’s Bay and the weather was just as great too. We could walk among the Eelgrass and Golden kelp Laminaria ochroleuca. There were lots of Snakelocks anemones Anemonia viridis around; especially striking were patches of what must be clones. The tentacles are much shorter than the ones in my aquarium or those found deeper on kelp, must be due to being less exposed to the waves. Loads of fish as is usual here, a single overturned rock yielded five species alone! Again pictures of the Connemara clingfish Lepadogaster candollei, a Butterfish Pholis gunnellus (very wriggly, hard to get a good shot) and Tompot blenny Parablennius gattorugine eggs:
This site is sheltered and silty and some species are more characteristic for this habitat and much less common in Castle Beach in Falmouth. Examples include the Keyhole limpet Diodora graeca, the Elephant hide sponge Pachymatisma johnstonia and the Yellow-plumed seaslug Berthella plumula:
The diversity of seaweeds was very high and I think the pictures below give a good impression of that. Very low on the shore Bushy noduled wrack Cystoseira nodicaulis can be found; in this case almost as iridescent as is Bushy rainbow wrack Cystoseira tamariscifolia. We found some Beautiful kidney weed Kallymenia reniformis, here David Fenwick is taking a photo of it on his first visit to my local haunt. All in all one of the best rock pooling weekends so far!
