need help!! My electric blue lobsters dont eat

[jacksont]

Dear all,

Need experts advise for my 2 newly bought electric blue lobster...cherax tenuimanus...They have been with me for 2 weeks and until now they have not touch anh foor, I have tried hikari sinking pallets, prawn and also plants...

Some description:
I have put in a lots of hiding spaces by wood and rock...2 filters, one undergravel and the other one is internal filter...I am also doin 1/3 water change every week..I even get a chiller to bring the temperature to 23C knowing this species cannot survive more then 25C...There is also air pump for this 3 feet aquarium...

I am very worry because they dont looks ok and I think I may lose them....Anyone pls help to advise what should I do....Thanks....

I feed Krill and Hikari crab food.

We feed ours the same variaty of foods that we do the fish and you don't always notice them eating. Tank temperiture dosn't seem to effect any of the three variaties of crayfish we have and all of them...even the tiny babies we baught on line and grew out seem to grow and thrive even though we rarely ever SEE them eating.

I target feed mine. I use tongs and drop the food right in front of the cray.

Let me help you with a mis understanding that you have.

1st electric blue crayfish are North American Crayfish usually from Florida.
What you have is a Cherax and it looks like a Marron.
A Cherax is a Southern Hemispherical Crayfish and the Marron is from Australia.

"Unlike some other freshwater crustaceans, marron do not burrow to escape drought; this facilitates harvesting and ensures that the pond walls are not damaged (Morrissy 1992a). However, they are not as tolerant of environmental fluctuations as yabbies. Marron do not grow at temperatures below 12.5oC and grow best at 24oC. Above this temperature, marron growth declines rapidly and mortalities occur when average daily pond bottom water temperatures reach 30oC and above, depending on exposure time (Morrissy 1990, Morrissy 1992a). In sites where the water is cooled by persistent winds, farms have been relatively successful at the northern end of the extended range for marron. Marron will tolerate (though not necessarily reproduce in) salinities ranging from freshwater to 15 parts per thousand (ppt), but low salinities are most suitable for farming, as growth decreases when salinities are above 6-8 ppt (Morrissy et al 1990).

Marron live in waters which generally have pH levels ranging between 7.0 and 8.5 (Morrissy 1976a) but sunrise readings of pH in ponds on relatively successful farms may be in the range of 6.0 - 9.0. Excessive algal blooms can cause extremely high pH values and unstable dissolved oxygen levels. Oxygen levels should be maintained at or above 6 parts per million (ppm) and marron become stressed when levels drop below 3 ppm. As marron are susceptible to low levels of dissolved oxygen, the use of aeration is strongly recommended in ponds to maintain adequate levels and avoid stagnant bottom water or stratification (Morrissy et al. 1984, Morrissy et al. 1990). In general, the water quality experienced by the marron is reflected by the design and management of the grow-out system used."

I would suggest that you check your water parameters like Kh, Ph, nitrites, and nitrates.... That might be part of the problem.
Also any sinking fish food will work but if you can find one with fish oils(not fish trash) it may help to attract them to the food.

hey you got a nice looking lobster. well anyways i have been taking care of lobsters and crayfish for while . so thats happened before of what i did is take a feeder fish and put it under a rock and left part of the fish body out.

Fish tamer your such a noob, go drown yourself in your fishtank for abusing a fish like that. Even if its a feeder, that still is a horrible thing to do if its still alive!
