Had my black and white clowns a little over a year, along with a royal gramma.
it’s been a little hot in UK, tank temp 25c has fluctuated 0.5-1.5c most days for a week or so
Around 6 weeks ago I changed my aquascape with dry rocks and doses bacteria, this went fine.
Around 3 weeks ago I left on holiday for 1 week with my tank in my brothers hands. ATO was broken so he had to manually top/check salinity.
Unfortunately he left it slightly high at 1.028 for the week. The gramma had completely vanished. I am not sure if this was the cause for its disappearance, possibly it’s death although I also think this may be down to too much direct sunlight. I pulled every rock out, checked every crevice- it was gone.
I watched tank parameters closely as soon as I got back and back to regular water changes.
There was no spike in any parameters (ammonia, nitrates). I accepted my loss and continued blaming the mystery on the hermits crabs. Tanks been fine ever since. Coraline algae is growing quick on crab shells and walls.
Obviously marks have appeared today, and It would be a hard blow to lose the clowns too. Mainly on one side of body, so I am even crossing my fingers to the small possibility of some mucus from a scratch.
This is only the female, the male has some marks but they are too small to photograph.
