My office tank has been running a little hot lately (82-84+) . The room
temp hovers around 28°C at the moment, so the SAEs are near their max
temp?

SAEs aren't too fussy with pH or hardness, so if other fish are ok,
changes
in those didn't kill it. "Office tanks" are often small, and a small tank
+
hight water temperature mean too often low oxygen level. SAEs come from
flowing rivers and they are often the first fish to die when oxygen level
gets low. I have killed two SAEs by having a internal filter fall to the
bottom of a tank during a hot summer day: no surface movement, oxygen
level
low. SAEs died, a bristlenose pleco (also needs lots of oxygen) was
gasping
for air and just managed to survive but other fish (some bettas and
synodontis) weren't affected.

Also some medications might make the oxygen level temporarily lower than
normal. Somebody I know lost a school of SAEs after medicating a big tank
with something which probably affected the amount of oxygen in water.

Thanks Liisa,

The circulation in this tank (10 g) was on the low side. I have a small
Whisper filter that WAS really dirty when I did the water change. But even
when it's working at full capacity it doesn't move too much water.The Sword
jungle doesn't help matters either.

I'm going to add a small bubble wall and hope that the algae doesn't take
over. The current air stone and pump are way too much agitation. Although
the remaining SAEs seem to like swimming through it.


My 10 gal with the single SAE uses the Whisper Jr. filter with no
aeration.
