during my holidays I tried to photograph and catch some native species in the Lago Maggiore. cobitis taenia and padogobius bonelli (syn p. martensii) would have been great. I guess there were too much movements by tourists and the water was too warm (about 25°) so these species retired in an aerea only accessible with equipement. p. bonelli seems to be very shy anyway and not to catch without eletric equipement.
not so salaria fluviatilis: curious and abondand. it's called "cagnetta" ("cagna"=female dog) because of it's typical "head-up" position. a sweatwater-blenny (one of two species), changing colour according to the substrat.
some pictures

a male with tipical "helmet"

easy to catch alongside these walls covered with algae,, at least the smaller ones.

the large specimen - about 10 cm are not easy at all because of the hiding places in the bolders

I put all adult specimen back as it's still breeding season (april-july) - some nearly black-violet males in sight - and prepared a tank of 50 lt with original substrat

only 3 cm long

about 7 cm

about a dozen.
they are classified as "potentially endangered"=NT (despite the study in 2002=not endangered). there are plenty in this lake and in the Lake of Lugano too. on that place - 40x10 m - there were thousands. I know they are rare in France too. asthonishing is: <1° hardness, means no hardness at all. it is reported that they can adapt to saltwalter with no problems.

do you know something about the "guests"?

Cheers for the paper Charles! Here in Spain it's officially endangered and illegal to collect without a license as far as I know, and not many pristine populations remain. I've checked at least 6 localities where it was recorded less than 10 years ago and not found a single specimen. The Spanish authorities suggest numbers may have declined by up to 80% in the last 20 years. /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

Unsure on the 'guests' but will check for you as I have some reference material at home. Got some other stuff on the Salaria too so will send you later.

they have grown up to 7/11 cm and meet some problems with their housing.
so I had to offer appartments of different kinds. in april the spawning season is coming and they have to move in a larger tank. the dominant male is already chasing the youngsters around

just little sponge filters to be on the safe side. I've cleaned the surface only twice since july. I think it wouldn't be necessary, the water is always super clean. the two pictorum I lost may have even died because of the lack of food.

That's cool. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> I assumed Salaria would need it turbulent and well-oxygenated because the only place I've seen them was like that.

Wonder if you could keep the Unio fed with green water?

no turbid waters, at least not at the level of the habitat. the water of Lago Maggiore is very clean on the swiss side. that's why most species show a tendence to change the country. that's what fishermen ascertain. it's due to the fact that the sewage goes through defecators on the swiss side to 100%, not so in Italy.

I won't restart to cook this sort of soup, Matt /mad.gif" style="vertical-align:middle" emoid=":mad:" border="0" alt="mad.gif" /> from time to time a give the starter liquid like for some small fry. but green water or whatever would work.

I'll send you what I have Michael, and very nice pictures! Can you tell us more about the breeding? Did you manage to raise fry?

I have not yet tried to raise fry. This is the first nest I found. At the moment I am waiting for them to hatch.

thanks oaken

some more to show the variable colours
the "second" male

[Image Can Not Be Found]

tries to dominate the rest of the group

[Image Can Not Be Found]

the "big boss" won't show up on the set, even not for tasty cocktail-shrimps

[Image Can Not Be Found]

and another male loses instantly all colouring when the dominating male appears

[Image Can Not Be Found]

and is chasen away by the "second"

[Image Can Not Be Found]

[Image Can Not Be Found]

last but not least some females

Great work and photos Charles! Are the eggs so purple in 'life' and did you see any of the spawning behaviour?
