Montagu’s blenny Coryphoblennius galerita in a Microreef pico aquarium

Already a while back I ordered a tiny (‘pico’) aquarium from US-based Microreef, which has a beautiful range of aquariums, especially acrylic tanks which are suited for temperate setups due to their insulating properties. The acrylic tank I ordered was only two US Gallon (7.5l) and came equipped with an IceProbe chiller fitted in a HOB (Hang On Back) filter. The IceProbe is a type of peltier chiller, working very differently from larger conventional compressor-based chillers. I must say that when I first tried it out, the temperature did not drop by that much. Since I first wanted to set up a temporary tank with rock pool critters anyway, I did not bother switching it on. I will have to fiddle around with it some more though. Below a photo with an iPhone to show just how small this tank is:img_2860-2As a first experiment, I caught three Montagu’s blenny Coryphoblennius galerita from the pool described in the previous post. (See this dainty little fish in its natural habitat in one of Thomas Daguerre’s short clips here.)  I decorated the tank just with some pebbles and found a tiny (<5 mm) prawn as a hitch hiker. As a light, I used a cheap Arcadia stretch LED. The fish (and prawn) readily fed on frozen foods and generally were quite active. Below a short clip with the largest individual (still less than an inch in lenght) showboating. I have since released the fish as the tank and filter did not do that well with the heavy feeding. I have to think about a new setup, especially with the chiller working and critters that would not be suited to the larger tank (about which I will post an update next).
