I'm hoping someone may have some thoughts on this. I have a Scooter Blenny behaving lethargically and gasping (bottom of tank...though I wouldn't expect a Scooter to spend time at the surface, even if ill). The rest of the community is behaving normally.
The Scooter has been in the tank about 6 months. The system is a little over 2 years old.
Tank: 100 gallon reef with 6" DSB
, and one 55 gallon fuge with 6" DSB
, and a second 55 gallon fuge with 4 basketball sized chaito balls spinning (for water quality). Scimmer, UV
, and so forth.
Community: Bio-load in the reef is light at 4 chromies, 2 clowns, 1 mandarin, 2 scooters, 1 flame angel, 1 engineer, couple cleaner shrimps and some assorted clean-up crew critters. No newcomers to the tank in 3 months.
There is a large copepod population in both fuges and the Scooter has been accepting frozen mysis in addition to the pods
for many months, so I think nutrition is probably fine. There is plenty of agitation and oxygenation, so I think O2
is probably fine. Water parameters are all on target, tested twice, 12 hours apart after noticing his behavior. There are no signs of flashing, scraping, or other indications of ich. The UV
bulb is not past life expectancy. There have been no signs of aggression in the tank, and the Scooter has no physical signs of damage or disease...No sunken belly, no swollen belly...Just lethargy and gasping for 24+ hours now. Intakes and fans are all appropriately sized. Did a 20% water change ahead of schedule, just for kicks.
I did try to snatch him up for a fresh / methy dip...He won't budge when he sees my hand, but he is zipping off when he sees the net, so I abandoned that for now...Didn't want to stress him further.
Any ideas? Thanks in advance!
