Fish

When looking for pictures of the squat lobster, I realized I have quite some neat old pictures to post. I should have started the blog when starting up the aquarium to keep things chronological, I will use the next couple of posts to get rid of this back log. First the fish. I have two Rock gobies Gobius paganellus in my tank. The big one is voracious and after a feeding session has a visibly distended belly. It is a curious fish that often comes to check me out when I am taking a picture. It is beautiful too:

However, I will attempt to catch it and release it, as I suspect it to be a bit too large (three inches) and rash. My worm pipefish Nerophis lumbriciformis are very shy and they might be bullied by large gobies and blennies. I actually suspect the big rock goby to have eaten my recently disappeared beautiful little Montagu’s blenny Coryphoblennius galerita, a species I have only found one time:

A worm pipefish Nerophis lumbriciformis. To replace the rock goby, I will try to catch some Two-spotted gobies Gobiusculus flavescens later. This species is also beautiful, but smaller and it spends more time in the water column which is nice. It is not a rock pool inhabitant though; it lives among seagrass. I have seen many last year when snorkelling. I need to look into a good net to catch them! I had two  large Shannies Lipophrys pholis as well that I released again, I still have a small one left:

I also had three thick-lipped mullet Chelon labrosus in the tank. These fish are quite ugly as adults, but juveniles are nice, restless silver fish. All  fish mentioned above are benthic (hang around the rocks rather than in the water column), whereas this species mostly swims at the surface and so really adds to the aquarium. I released these three when changing up the tank once and I now regret that. They are fast swimmers so quite difficult to catch (at least with the small aquarium net I use). Since they are so restless I did not manage to take a decent photograph. I have also added a Shore rockling Gaidropsarus mediterraneus and the cling fish the Cornish sucker Lepadogaster purpurea at one point. I should have known that these were mistakes as these are fish that mainly hide under rocks and I have not seen them since adding them to the aquarium. I will post some pictures of these fish in their natural habitat later.
