May I add coral while running fallow ???

[Jonathan blackwood]

Due to my recent outbreak with ich :/ I just removed all my fish and transferred them over to QT. While this is happening, my tank is obviously fallow . May I add coral and inverts to the tank while it's vacant? Or will that effect the "fishless cycle" to remove and die off ich...??

Yes you can add corals and inverts but with each introduction you risk introducing encapsulated marine ich again, possibly resetting the fallow clock.

Because they would be "hitchhiking" yes?? There might be a chance the tank it came from might have been infected. Or another reason ?

Protomont: The stage where the parasite drops off the fish, before becoming a tomont. Protomonts crawl around looking for surfaces to encyst upon.

http://edis.ifas.ufl.edu/fa164
Once a trophont leaves the fish, it becomes a protomont. During this phase, it loses its cilia, flattens its surfaces, and moves onto a substrate for about 2–18 hours. After this stage, the organism stops, sticks to the surface, and encysts, whereupon it becomes a tomont. The cyst hardens in about 8–12 hours (Colorni 1985). Before the cyst forms, the protomont may be susceptible to some treatments for a short period of time. However, once the cyst has formed and hardened around the tomont, it has greater protection against common treatments

Tomonts range in size from 94.5 x 170 µm (~ 1/10 mm x 1/6 mm) to 252 x 441 µm (~1/4 x 1/2 mm). The tomont of one strain of Cryptocaryon was 210 x 763 μm (~1/5 x 3/4 mm). The encysted tomont undergoes many divisions, producing numerous daughter tomites (approximately 100 to 1000, depending upon strain and temperature [Colorni and Burgess 1997]). These tomites are released as theronts, the free-swimming infective stage.

The time required for theront development varies. In one study (Colorni and Burgess 1997), theronts emerged from a group of tomonts sometime between 3 and 72 days, with most released from 4 to 8 days after tomont formation. In another study (Diggles and Lester 1996c ), tomite development and theront release occurred, on average, between 5 and 12.1 days after tomont formation, depending upon strain and temperature. There was no correlation between tomont size and theront release. Yoshinaga and Dickerson (1994) observed, in laboratory studies, that theronts were released only between the hours of 2:00 am and 9:00 am, even in total darkness; some suggest this strategy increases the chance for theronts to find a host, as many fish may be resting or closer to substrate during this time period.

From the disease section, hope that helps to clarify it. But it's a double edge sword because most hobbyist do not QT corals and inverts so there is a risk of re-introduction after the tank has gone fallow and the fish treated. Personally I would add corals, because the risk while present is still low and I am more of a coral than a fish person.

Because a tomont could be hitchhiking in on a coral or invert; IF that were to happen (no way to know for sure) it would reset the 76 day fallow period.

Ok :/ shoot... thank you very much

Sorry I realize this is an old thread but didn’t want to start a new one if this is exactly what I was inquiring about...

What if you freshwater dip the frags before putting them in the DT. Will the ich fall off the coral in the short amount of time the coral can tolerate a fresh water dip? Are there any other coral dips that will kill ich? If not, could you do the tank transfer method with a frag rather than a fish? I have gone through extensive QT with all my fish and coral as well as the fallow period in the display tank and have all my new coral in a separate fishless coral only QT. I’ve just added the last of the frags that I plan to buy for while and am going to run them in that tank for another fallow period if there are no other options.

Also, does anyone know if you can test your tank to see if you have ich? Like with a sample from the water column and a microscope or something...? That would be awesome if someone came up with a test kit for that.

This will explain. In short, no, you’ll need them running fallow. Should you add most items, it restarts the 76 day clock.
