hi i am in the middle of getting a tank setup for my son to keep red claw crabs. the thing is in the lfs they are kept in freshwater. from the research i have done i have found they are better in brackish conditions. should i set up my tank to be brackish right from the beginning or should i keep it freshwater and then increase the salinity with each weekly water change. i'm a bit worried that the crabs may be affected if they are just put straight into brackish from fw cheers in advance for any answers
i think your on the money their set up as freshwater search the site for fish less cycle to get this right then get a refractometer to measure the salinity accurately and slowly increase it to brackish conditions over a few months
please don't get the crabs before you have cycled the tank it will only end in disaster inverts are very sensitive to ammonia and nitrite and a colony of bacteria must be grown in the filter to allow these toxins to be turned into nitrate which then gets diluted with weekly water changes
could you list your tank size/dimensions and filter make model please as well as the tank set up
the tank is all ready cycled lol theres no way i wouldn't do that.
i also did my usual of thoroughly researching the crabs just didn't know how to get them to the brackish conditions that they need without harming them.
managed to get 2 today, unfortunatley the shop had kept them extremely crowded with no hiding spots etc and all the crabs had limbs missing. managed to get the 2 best ones and i'm keeping my fingers crossed that they will do ok. they seem to like their tank though. it has land for them as well as water.
no problems bud we get so menny new keepers hear that are so miss informed that we just don't know the level of knowledge of a new member so many questions are asked sometimes its like teaching to suck eggs and all that but all the better for it lol
just one more thing we like picky s hear lots and lots of picky s lol
cheers for the link. one of the crabs has molted today, it's hiding at the mo. think the other one will later today as well. my son thinks it's brilliant lol. will be doing a water change at end of week so will add a bit of salt to start the slow change to brackish. thanks for all your help chrissy
