Whts The Deal With These Large Black's Dropping Off???

[ausarow]

warm clean water should trigger feeding response.
barometric pressure should not be a reason for internal problems.
though it sure can affect feeding. there are a few schools of thought on this.
one is that winds or rain ( change in pressure) will blow more insects etc from trees or flood them off the surrounds and the fish are on the ball for those times.
another thing can happen too though. when cloud comes over in an algae laden pond or lake etc and drops the level of photosynthesis the fish might become less active and so become less interested in food.
how the fish picks up on this is hard to say. you would imagine that a change in atmospheric pressure would slightly change the pressure the fish feels and sure fish could be set up to feel it but to my mind the fish would feel the change when it goes from the surface to a foot down. ruffling of water and rainfall and lack of oxygen and light might be most obvious to a fish.

out of the blue mine stopped eating a few weeks ago and is starting to drop the end of his tail and swim funny

same thing happened to keepinfish's black not too long ago also

is this common w blacks? wht is the cause?

should we be keeping these guys in groups so they dont get depressed???

i have had mine for a while too. maybe close to 2 years? I dont remember exactly. always ate good. Mine was drooping the end of his tail and acting weird.

My only thought was my tig has been acting up lately, as soon as the lights go off he would go nuts. i wonder if he spooked my black. I lost a silver the exact same way a few months before and the tig was not with him though.

It seems a few have died lately, and it makes me wonder, same kind of thing with the armatus that die suddenly?

This is very interesting, I have seen my blk arro swim with his tail down, but its usually when I do a water change, not just out the blue. Could it be once they reached a certain age, as mine is about 3yrs old at about 20-22inches?

my blk aro is still alive. hes swimming a little funny still but otherwise looks perfectly healthy

he hasnt eaten in about 4 or 5 weeks now all of my rays in the same tank are still eating their 2lbs of food per day, all params are perfect, i have no idea wht the problem is

what do u guys think about me pulling the aro out and force feeding him a few earthworms to get his appetite going again?

 

[ausarow]

he got stung by a ray and isnt feeling too well?
tried cockroaches? they seemed to trigger my jars into feeding.
what are temps now?

he could have got stung but there are no visable scars. all my rays are very feisty though so i guess we will never know

ive never fed cockroaches b4 but i did try feeders and earthworms.... with no results

starting to loose his balance and letting the powerheads push him around

Fish in tanks as in the wild are more active and feed when the barometric pressure is high. An old Aussie Toga (Lei) fishermans saying "1020 fish aplenty, 1008 sleep in late"

Man i was looking at Black aro threads and don't wanna see this one.. My 30" Big Black stopped eating like 2 weeks ago and won't touch anything i drop in the tank.. I hope my big black isn't the next on the list to go.. Hope yours get's better before you have to put him down..
