Need to qt inverts from divers den?

4FordFamily · Jun 4, 2016

I only ask because my clams are struggling in my "established" invert qt and I think they would thrive in my DT.

If I knew of an LFS that kept inverts separate from fish I would buy them up in a heartbeat because theoretically then they couldn't harbor fish ailing parasites?

Anyone know the process for inverts at DD? Worth the risk? I have lots of really difficult to keep, expensive, and otherwise intolerant of parasites fish I don't want to risk, but I figured I would ask!

I'll ask my friend. She worked there.

Is it aquacultured or ?

I would send them an email. I'm sure they would share their procedures with you

Yea the ones I buy are aquacultured clams

Yes

38 days of isolation should protect you (tomont + theront), except for the 72 day variant. See below.

But I guess my question is that if I understand the distribution system properly, clams are often kept separately from fish (and many inverts are) primarily due to the fact that they cannot tolerate medications like low levels of copper and the low salinity that they're often kept at, 1.015.

If aquacultured I would think this would be further improved, and then divers den theoretically adding another 3-4 weeks of a safety net.

Is my logic sound? Humble you are the man you've been right every time you've suggested something to me!

Where is the 72 day one?

The problem is I don't know how isolated DD keeps their aquacultured clams from their fish specimens. Remember, its not just being in the same tank you have to worry about. Sharing water through a common sump (or if the systems were plumbed together) could transfer protomonts into the clam system. We know DD specimens are not necessarily free of ich.

That comes from the 1997 Colorni and Burgess study (excerpt below): http://link.springer.com/article/10.1023/A:1018360323287

Even under identical incubation conditions tomonts vary considerably in the time required to form theronts (Nigrelli and Ruggieri, 1966; Colorni, 1992; Burgess and Matthews, 1994a; Diggles and Lester, 1996b). Thus, theront excystment is very asynchronous, occurring between 3 and 72 days and peaking at 6 ± 2 days (Colorni, 1992). This differs significantly from I. multifiliis, where the theront excystment takes only 18-24 h at 23C (Dickerson and Dawe, 1995).

The reason for asynchronous excystment is unclear. There is no relationship between the tomont size and excystment time (Nigrelli and Ruggieri, 1966; Colorni, 1992; Diggles and Lester, 1996a,b). In fact, a large and a small tomont may produce theronts at the same time, even though the smaller tomont undergoes fewer divisions. When tomites do not form until at least 2 weeks, a mass of endoplasm remains undifferentiated and fewer live theronts are produced (Colorni, 1992). Whatever the cause, asynchronous excystment prevents simultaneous exhaustion of all tomonts, facilitates theront dispersal in time and appears so advantageous to C. irritans that the phenomenon should be interpreted as a strategy for survival (Colorni, 1985).

Yup, I have heard though that their fish systems are different because of the medications present, not sure if the salinity is lower as well as it is in many distributors. Blah. That's all. Blah.

shoelaceike · Jun 5, 2016

What kind of invert?

shoelaceike · Jun 5, 2016

Oh, clams

I don't think they usually dose meds into most of the tanks. They are all about doing dips, baths and delivering meds via food soaking. I've never understood their logic when it comes to soaking praziquantel to battle flukes - since the flukes primarily live inside a fish's gills and not in the intestines. I suppose they could be doing it to eradicate intestinal worms and administering long term baths for flukes.
