I shot the fishes (but I didn't shoot no deputy)

Beautiful colourings on the Procambarus alleni it is a species of freshwater crayfish endemic to Florida. Its natural range is the area east of St. Johns River and all of Florida from Levy County and Marion County southwards, as well as on some of the Florida Keys.

Thanks Keith. Those are the crustaceans I like the most. I nearly got 10 photos of it (most crappy unfortunately).
In fact they were 2 in the tanks. Living the same way as my CPO does ; just in different scale :p
 
Hi ptiJo , Love the name of the thread:LOL: Fab pics (y) And i love jellyfish its just the way they move and hunt :rolleyes:
As to crayfish we have a big problem in England with American red signal crayfish they are over running our rivers lakes and ponds and wiping out our native crayfish and feeding on fish eggs to Nasty things :(:( Fantastic eating though :D
 
Erf. Do you mean Procambarus sp marmor ? I think I read it was also doing too well here. ; as it survives outside, even in winter. And the fact that it's parthenogenetic means only one can lead to the ruin of a pond... Although I know some who breed it to feed fishes :p
 
Hi ptiJo, No its Pacifastacus leniusculus Real nasty little critters:eek: And they can survive over winter too :(Big carp and chub can eat them but not enough to make a impact on there numbers and now there getting everywhere :mad::(:(
 
Hi ptiJo , When someone brought them over hear to breed and then sell to eat and make money(n) No one told them that they can clime out of the pond and cross land to get to new feeding grounds :( Stupid people will they never learn :mad:
 
Well, I didn't know either until I was told. And I just saw a video on uTube showing a Blue Crayfish "walking" on a stock of leaves ; between to water point I guess. I thought those would not last more than a minute without water...

Sounds like you have a very nasty import there in the UK .

I have something similar in our LFS.

Hi ptiJo, So long as its damp they can stay out of water for hours :( They are a bit clumsy on land but can be very fast in water they swim backwoods with a flick of there tail and there gone:)
 
Hi Keith, Very nasty they are devastating our water ways :(:(So they say in one mile of river there could be thousands of them munching there way through our natural stocks :(:( With very little to stop them as always with imports there is no natural predator well apart from big fish but as i said they have very little impact on there numbers :mad: Such a shame if you go fishing and put a bait on the bottom all you will get is crayfish and they eat anything even sweetcorn :mad:
 
Slighty out of topic but as I opened this thread, I can pollute it :p

Here my outside tank (about 20L), laying on my balcony, 3rd floor in Paris. It's out 24/24 7/7 and must deal with Winter. It already went through one without issues. It's really lazy on the layout as I just dropped a spare driftwood and planted whatever spare plant I had and/or wanted to test outside. I clean the front glass 3 or 4 times a year and only take algae out when DW is not visible enough any more (I think I had to do it only once at the end of Summer :).


So far, Vesicularia Ferriei Weeping Moss did well with a few days of frozen water. So did Lemna trisulcaL. Note that the tank never fro zed entirely last year.
 
Hi ptiJo, Well you cannot get any more low tech than this little one :) Fantastic idea just let nature do its thing :rolleyes: Up in the LH corner is that a coke bottle bottom used as a planter :unsure: If it is what plants do you grow ?? Love the floating plants. Overall one fab little Aquascape :rolleyes::rolleyes:
 
Thanks! Yep, up left is a (water ;) plastic bottle filled with sand. I did a couple of tiny holes so that water flows in straight from the tank. Some roots even found their way through them :) There are a few things trying to live in. What works well since the beginning is Cyperus alternifolius.


There are some other things on which I do testings. Namely an Ivy branch that I expect to have developed roots now. There are a few cuttings of Equisetum scirpoides and Soleirolia soleirolii that seem to do well too. A few days ago, I added a bit of forest moss that seems to like to get moist (tested inside in some riparian) ; no sure how it'll do.

If you're interested in pictures, you can have a look at my DIY-Balcony Pond. It is "Tank vs Wild" too ;-D
 
Hi ptiJo, Thank you for the link(y) WOW that's is Stunning :rolleyes::rolleyes: So much growing in a little space :cool: And the pics are superb (y) One Q whats the name of the red floating plant i love it :)Well i like them all:LOL: Will look into the plants that you grow in the water bottle they sound fab. And thank you again for sharing ;)
 
Thanks a lot ! My pleasure :)
The red one should be "Azolla filiculoides" aka "Fairy moss". I usually write the name of the plant or animal on every pics (top banner). So that I can remember their name later on :p

We have FW Crayfish (yabbies) in our water ways they make wonderful eating.

Easily caught I Panty hose with a piece of old meat in it wait a few minutes and pull them in.

:) It seems to be getting red only when getting direct light from the sun. When I got them, they were green. Those transferred in that cubic tank got direct sun light and went red. Others, send to some other external tank got direct sun light and went red too. Those left in the pond, which get no to very low direct sun light, stayed green. Some I took inside got direct light from my LED lights and never turned red. I guess then need UV (or some other invisible part of sun light) to turn red ; like Brits ;-)
