Sooo, after a longish overhaul, ridding all the plants and some minor rescaping, I'm finally getting this tank back in gear. Curing: https://www.youtube.com/watch?v=eedpYQbCjIw   Thanks for looking!

An exceptional winter around these quarters. In my lifetime, it's the first time sea has not frozen up all winter at my base camp in Hanko, Finland.   Thus, open water net fishing (food kinda) has been possible.   A bycatch from last weekend: Nerophis ophidion, Lappohja, Hanko, Finland.   We...

Thanks for showing interest in the project, Mads.   Salinity seems to be pretty stable at SG 1,005-1,006 on these waters. So yes, very low end brackish.

Thanks for your interest, folks.   Some more test fishing for prospect inhabitants this weekend resulted in a few Myxocephalus quadricornis. Male:     Female:   Back in the sea after posing     These guys are a bit too large for the tank at 25-30 cm. But it would be interesting to see some...

Everywhere we go, M.   The credit for finding the seal goes to our faithful companion on the project, Walo   He thinks animals are kinda cool.   He enjoys work onboard the M/S ApoCalypso     Now down to the serious business. I salvaged this beer tap cooling element from a bar I built   It...

A very depressing find on one of my trips this summer was this Halichoerus grypus   A closer look at the animal revealed the reason she was dead:   A seal researcher agrees these seem to be bullet wounds. Whether the kill has been legit or not is hard to tell. But upwind from the location the...

The first sweeps with a net on this rocky island   resulted in this catch:   Cottus gobio   Phoxinus phoxinus   Pomatoschistus minutus   And a shrimp only lately introduced into northern Baltic sea, Palaemon elegans.   A glimpse of other fauna on the baltic, here's a flock of Phalacrocorax...

Hi, Mads!   Nice to hear someone else is interested in the largest brackish pool in the world.   The difference between the Baltic Sea at your latitude and mine is that there really is no tide at the northern shores. The very shallow inlets around Denmark control the amount of water Atlantic...

      Oh, there's some very nice life below the surface. Not nearly the variety of either fresh of full marine, but some very interesting life.   Osmoregulation abilities of the reproductive phases of creatures is pretty much the key in tolerating brackish. Some have it, some don't. Surely...

Sorry to read about your 'skipper, too. What a freak accident. The personalities of mudskippers really make them pets.   I agree with you, barbarus will never tolerate each other, as long as there's a visual contact. No matter what gender they are.   Better luck with the remaining fish, I hope...

Hello, you brackish you.   My spiritual home for many years, Baltic sea.   It's about time to start making a biotope based on the upper northern parts of this sea, namely Gulf of Finland, northern shore and a bit of Sea of Åland and the archipelago.   Salinity is around 1.005 SG on these...

I don't think there's "being bored" in the mind of a fish.   Take swimming up and down the glass as exercise. An option for commuting a distance from where it is. That is, of course, supposing that the water quality is to it's liking.   I've got two GSPs in a tank and they are doing great. They...

I'm not at all certain about it, but I have a feeling reds have enough energy in the pod only to grow roots down to the substrate. And if they don't reach it, they don't get enough nutrition from water to grow. I know, some people seem to be able to do it, but still...   I killed ten of these...

Hello there.   The mudskipperarium is still under attack by the bugs, haven't had time to tear apart, treating all flora with pesticide and restarting the whole thing yet. Black mangroves are suffering and losing leaves and looking sad. But at least I know the reason for it.   Have your reds...

Unbelievably nice coverage on mangroves, M. Thank you.
