|
| Hi all,
|
| What could cause previously healthy SAEs to die suddenly? As in a matter
| of hours?
|
| What's happening:
|
| I (used to) have five SAEs in a heavily planted 125-gallon tank with a
| UV sterilizer. These guys are three years old, fat, healthy, bright, and
| 3-4 inches long. They stay very busy doing their SAE thing. No signs of
| illness.
|
| Friday morning I wake up and one is dead. The night before he was
| healthy, swimming well, etc.
|
| I do tests. pH is normal (6.6-6.8), no nitrate, no ammonia. Noontime
| oxygen is good. Because I've been concerned about nighttime oxygen, I
| install an airstone for those hours, just in case.
|
| Things appear to be normal until Monday night, when I watched one, who
| was previously healthy, roll over on his back and die. No warning. Just
| dead, almost within a matter of minutes.
|
| There are only three clues:
|
| 1) A pH spike Monday night to about 7.2
| 2) Added 7 rummy nose early last week. Lost one or two.
| 3) The four dubawi cats are looking peaked. They'll lie on the bottom as
| if about to die, then return to normal a few hours later.
|
| What is going on? Some kind of catfish plague? All the delicate
| cardinals and rummy-noses are fine. The CAE and clown loach are fine.
| The three shrimp are fine. A sick, ancient bleeding heart left over from
| another tank in another era refuses to die. The three or four neons with
| neon tetra disease keep hanging on.
|
| I've added nothing but fish food, the rummy noses, and two five-gallon
| buckets of water in the past week. No chemicals, no fertilizers. The
| last 1/2-tank water change was about two months ago (the plants hate it).
|
| I need as many opinions as I can get on this, so fire away. I'm afraid
| this isn't over.
|
| Thanks.
