Hey Guys,

I've been browsing the forum lately, and i've heard people (BB) talking about F1,2,3,4,5

Can someone explain to me what these terms are? i might guess they are generations?

Yes thats right Masta. F1 stands for the first generation. F2 the second generation, and so on. Typically you dont see mention of F generations beyond F1 or in rare cases F2, because by the time you get to the third, fourth or fifth generation, the individuals don't necessarily have the same characteristics as the originals.

So for example, if you obtain wild caught individuals and you breed them, the offspring are wild-caught F1. By the time you reach the third generation F3, its not worth calling them wild-caught F3 because the individuals you have will be adapted to aquariums and have different characteristics to the original wild caught adults (e.g. hardier, tolerance to a wider range of parameters, possibly larger, easier to breed, readily recognise commercial foods, ect ect).

Good one Ben and I am so glad you mentioned the adaptation to Aquarium conditions and life, so many people over look that one.

      Finally set up the 30L Shrimp Tank

      By sdlTBfanUK · Posted

      It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

      Pure Red Line (PRL) Shrimps Western Australia seller

      By sdlTBfanUK · Posted

      I believe these to be very rare in Australia so you may even consider making it a longer term plan and produce your own by starting with the best CRS you can get as that is where the pure lines started! Depends how patient and interested in the project you are, but would save money as well? If I recall correctly it takes from 8 generations of selective breeding? They sell them at micro aquatic shop but do not ship to Western Australia, but that means they are available in Australia. https://microaquaticshop.com.au/products/pure-red-line-grade-ss-shrimp Good luck and just maybe smeone on here may point you in the right direction or be able to supply you with some.

      Is this garden hose end alloy pipe safe to use for aquarium piping?

      By Subtlefly · Posted

      Yes it’s super accurate to position where I want now and stay there- I am satisfied.  All the fish and shrimpers are doing excellent! Coming up on 4 years running!

      You must be pleased with that, it looks better and is much more robust and less likely to damage or leaks! The tank looks very natural now it has been running for a time. I see the ember tetras, how are the blue shrimp doing, I see a few? The cat and dog look very content and unimpressed, lol.
