Monster Feast (Dan Neal's Grendel)
This tank setup works remarkably well as a mantis shrimp habitat. I was originally planning on using a spare 11L (3 gal) Eclipse tank to house a mantis shrimp, but since Grendel is about 15 cm long I thought he'd do better in slightly larger accommodations. This tank previously housed a single orange-tail damsel (Chrysyptera cyanea) who, unfortunately, perished when my tank hit 36°C on a horribly hot day. By using the clip-on fan, I've been able to keep the temperature under 27°C in hotter weather. Without the fan, the tank runs at about 27.8°C to 28.9°C. Understandably my heater gets very little use.
Maintaining Grendel's habitat is really a
simple affair. (Providing he doesn't shatter any of the bones
in my hand when it's in the tank Caution
is the word when dealing with a 15 cm mantis shrimp!) I've
been able to maintain ideal tank conditions (salinity stable
at 1.023, pH is 8.0-8.2ish, and no detectable ammonia or nitrites)
with the following routine:
I usually feed it either the freeze dried krill or a single cube of frozen formula one every other day. It also gets a small feeder goldfish as a treat every month or so -- I know a diet of only feeder goldfishes would be quite unhealthy, but it really seems to enjoy catching them as a rare treat.
