My fiance and I have a 125 gal coral reef tank. Here's what we'd like to know about
1. We would like feedback on adding a morrish idol to an established tank. We've read up and know about the feeding issues. Do they eat corals? We have mostly sps and a few leathers/ricordia/zoanthids. We've read conflicting reports.
It is compatible with most fish and larger invertebrates, but should not be kept with any polyps or corals, which it will eat. Small invertebrates may be threatened as well.
2. We would like to add a pair of blackray shrimp gobies and a Randall's pistol shrimp. We have a substrate consisting of aragonite and live sand, about 3", and about 225 lb live rock.
a. Any feedback about the pistol shrimp killing tankmates?
That is a nonissue. I even keep nonsymbiotic pistol shrimp (those not associated with gobies) with no issues (alpheus soror)
If pistol shrimp are virtually blind, how can that be? We've read that the gobies help the shrimp because of its poor eyesight.
b. We read an article about acclimating the pistol shrimp and gobies using a piece of pvc pipe buried in the substrate. Any details on this technique? What size pipe should be used? Is the pipe removed at some point? Is our substrate appropriate for this technique? If the pipe is removed, is there a chance that the gobies will burrow under the rock? We'd hate to have our rock become unstable.
Pistol shrimp will burrow where they want; you can put in 3/4 inch pvc but there are no guarantees
Thanks in advance for your help.
