I'm sure the SPS corals are stressing a bit because of ammonia build-up, though, and not from what caused the fish deaths.
phil519 said:wild guess here - but if the cuke were annoyed "while you were out" and decided to eviscerate...it's possible all fish would be killed rather instantly - especially in a smaller volume tank like yours.
Article on Cukes
I hope that is not the case - but the only thing I can think of is perhaps the cuke eviscerated and your fish were foolish enough to eat the stuff.
Life Cycle of Amyloodinium:
This parasite is most often "brought in" to a new system from newly acquired infected fish/es, but may be acquired and passed on invertebrates, live rock, algae... most anything wet. Hence the need for diligence in selection, acclimation and quarantine. It's life cycle is almost identical to the more-familiar Cryptocaryon (Saltwater Ich) protozoan.
Almost always, the gills of fishes are affected... way ahead of apparent marks on the body or fins. Rapid gilling, apparent inflammation and irritation of the gills, followed by labored breathing, sedentary behavior, may occur so rapidly (hours to a day or two) that no other macroscopic evidence of its presence may show. Light, resident infestations in captivity (unlike Crypt) are rare... With most captive cases resulting in rapid reproduction, re-infestation, gill necrosis, hemorrhage and death.
Free-swimming infective dinospores, have an apical flagellum and one at the waistline in a groove, red eye spot, measure 9-15 microns. According to Bower (1987) dinospores can usually live for 7-8 days without finding a host and are infective for 6, remaining alive and infective even longer at lower temperatures. She recounts that though most emerge from encystation within 5 days and survive another 7 to 9 days, some dinospores were present in their test tanks (at 75-80 F.) some 37 days later.
Non-motile feeding stages (trophozoites) that parasitize the host fish (become attached to gill epithelium or skin, lose flagella, develop a funnel-shaped aperture at one end through which projects rhizoids to obtain nutrition. As Trophozoites grow, internal structure becomes obscured by globular starch granules. Trophozoites range in size from 15 to 150 microns, have a round to oval macronucleus. Their cell wall membrane is sharp and clearly visible, contains chitin.
When they mature (3 days to a week) they drop off and fall to the substrate where they encyst. Cysts are formed by the cells retracting rhizoids and sealing the opening with a cellulose cap. Here what are now known as tomonts undergo vegetative (non-sexual) division. Internally dividing cells called...
Palmella stage. Asexual division results in 2,4,8,16... 256 individuals formed. There is no division below 50 degrees F., slow rate 68-77 F. Optimal above 77 F. (25 C.) Hosts rapidly show signs of infection 6-7th day at 77 F. Note: there is no dormant or resting stage. One strain lasted w/o fish for 4 weeks, but not eight at 78 F. Invertebrates can carry this disease.

Size: 1 - 2 Inches
Care Level: Easy
Temperament: Docile
Origin: Aquacultered
Minimum Aquarium Size: 10 gallons
Reef Compatible: Yes
I managed to get my hands on one of Oceans, Reefs and Aquariums "ORA's" most sought after aquacultured specimens, the Picasso Percula Clownfish. This little guy was purchased from House of Fins in Stamford, CT. According to the store sales people he was a Grade: B Picasso and because of that many people had passed on purchasing him, but not me. This little guy deserved a home in my aquarium and was purchased for a super sale of $80.00 (normally priced at $120.00). Hopefully in the near future I can locate a second Picasso Percula Clownfish to introduce.

Aquatic Obsessions has 2 of them right now. I think they are only charging $50 for them and they are a club sponsor.
