FAQs about Snowflake Moray Eel Disease/Health – 10/22/08 Hi
WetWeb Crew <Hello Katie.> I have had a snowflake eel for 2.5
years (from about 20cm to 40cm long). For the first year he was very
active and got very excited at the first smell of food entering the
tank. He ate anything and everything. He loved mussels, prawns, squid
and Krill (fortified with vitamins). For the last six months he has been
very reclusive and fussy with food. He spends most of his time hiding
behind rocks in his conduit home - he used to be a lot more social. He
used to come and eat out of my hands at the top of the tank. Now I have
to take the food and put it in front of his face. He won't take the
mussel or prawn anymore, but will eat squid and krill. About six months
ago the area on the top of his head became white. This white area is
getting larger over time and I am getting quite concerned about him.
<Understandable, can be serious, fatal.> He doesn't come out much
anymore and doesn't seem to have much energy. Do you have any idea what
is wrong with him? <You did not mention the size of its tank, water
quality or co-inhabitants. Check the water quality first. Long term
declining health is often related to bad water quality. Nitrates should
be below 20 ppm at least. If they are not, do a series of water changes
until they are and re-think your filtration system. Also check pH, which
should be above 8.0 and the salinity. If the nitrates are below 20 ppm
all the time and the other parameters are okay, too, I would consider a
lack of nutrition. All the foods should be soaked in vitamins at this
stage, and personally I’d stop feeding krill until its health improves.
In addition, it does not have to be fed every day, feeding every few
(2-3) days is fine for a 40 cm moray.> (I don't actually know that
it is a male - looking through the thread though it's interesting that
everyone thinks their eel is male!) <The small Echidna nebulosa are
mostly females, larger ones often males. Size is not a 100% gender
indicator. With a little experience you can see if you’ve got a male or
a female by looking at the front teeth. Males have longer front teeth
with fine serrations. That seems much more reliable than size.> Many
thanks for your help. Regards, Katie <Good luck. Marco.>
Breeding snowflake eels Since I am going to take your advice and
go with the snowflakes, how many would be able to fit in a 55g?
<that would be relative to size and time held there. Many juveniles when
small but alas this will not help you. They do not pair up or life-mate
conspicuously as some other fishes do. And as such, two adults at 18-24
will be perhaps too much bio-load for a 55 gallon aquarium if fed well
enough to be kept in breeding condition> I would like to get about 5
of them cause my chances of having males/females would be greater.
<agreed on the statistics, but I have no idea on how to help you sex or
find a pair> Also what is there temperament like? <overall very
well behaved> Could I stick my hands in the tank? <usually yes,
but all eels must be respected and watched carefully> I am going to
try and use the wooden squire to feed them off of cause I would know
they were eating and it would also be neat. I Will get to work on this.
Thanks a lot! <agreed... feeding tongs and skewers are always
recommended with eels> John P.S. Any extra advice? <alas, no my
friend beyond good fish husbandry (varied diet, superb water quality,
large aquaria, etc)... you have the exciting challenge of being a
pioneer to teach us all! Anthony> Snowflake Info
Anthony, I may have some help for you. Considering all of the advice the
WWM crew gives me, I figured I could return the favor. <much
appreciation!> I know little about corals, plumbing, etc., but I know
snowflake morays very well. I have had my present specimen for seven
years and a previous one for two. John wrote you yesterday asking about
sexing them. They are suspected to be protogynous hermaphrodites.
<ahhh, yes... many eels are hermaphrodites. I did not know this about
snowflakes> Basically, there is a school of thought that some
Snowflakes apparently "change" into males at about 17", their teeth
become sharper and more serrated in the upper jaw than females. Have him
read Scott Michael's Reef Fishes Vol. #1 for a good outline on this
species. Michael refers to this tooth phenomenon. <excellent
reference!> I had read a slightly different account of this elsewhere
also. My snowflake is approx. 28", and I have noticed that the teeth in
his jaws and roof of his mouth have indeed become more sharp, in the
shape of arrowheads. BTW, this change occurred sometime after he reached
20" -- <very interesting!> I didn't notice specifically when. I
cannot state that "he" is actually a male, as I have not attempted
breeding him. <try placing a TV remote control on one side of the
tank and see what side he migrates to :p > Also, reassure him that
Snowflakes are indeed quite mellow 95% of the time, never bothering
other tankmates. I can handle mine in non-feeding situations. However,
at feeding time they often get very boisterous, snapping at everything
in their search for food. I've been accidentally bitten a few times and
instantaneously released after mine realized his error, but nonetheless
he drew blood. An adult's jaws (not just the teeth inside) are sharp and
unbelievably strong. <not to mention remarkably unsanitary... needs
good medical attention often> Feeding tongs are certainly advised if
he intends to feed several at once. FYI, they love supermarket squid,
scallops and shrimp (fresh, not canned). Buy a 1/4 lb. at a time and
then toss in the freezer to kill potential parasites, etc. before
thawing out portions to feed. <excellent point about freezing... and
yes, Squid (tentacles!) are especially stimulating to eels> A great
animal! Hardy and long-lived too -- mine was 17" seven years ago, so
he's probably 10+ years old and showing no signs of advanced age. Wish
John the best of luck. <your kindness will be repaid in kind I'm
sure... thank you> Anthony, one quickie for you: I know you dislike
siphon overflows and powerheads, <true for most tanks yes> but I
will need more circulation in my tank upon its redesign...Long story
short, I cannot drill a 2nd overflow. So, which is the lesser of two
evils for circulation only, two Tunze powerheads or a siphon overflow
hooked up to an external pump? <the Tunzes are AWESOME! And I would
NEVER sleep well in a house with a siphon overflow system... too many
overflows and fires/hazards> I'm leaning toward the Tunzes due to
fear of potential siphon or return line leakage/spillage someday.
<failure is inevitable in the 3 year picture for most overflows...
really the 1 year for most> If you prefer a siphon, which brand for a
180g? <I literally wouldn't take a siphon overflow for free...
rather pump up to a refugium and use the display for a sump to get max
flow in a two tier system> Thanks. Steve w/Predators. P.S. The
Ginas from Providence told me they are immune and unafraid of your
"garlic force field" :) <outstanding... now if we can only find some
that are attracted to men of Mediterranean extraction that look like
they are wearing Mohair pajamas with their shirts off. (Ha! Chia pet
chest) :P Kindly, your furry friend... Anthony> Snowflake
Romance Hi <Hi, Mike D here> I was wondering if you know
anything about Snowflake eel reproduction?<Not as much as I wish I did.
I've been told that Snowflakes are protogynous hermaphrodites that
change sex as they go through various stages of their life, much like
groupers and wrasses.> I have a Snowy who has become rather
active, before I was lucky to see him, but now he swims in and out of
the rocks apparently looking for some thing.<This behavior seems to be
related to growth and security more than sex, with larger animals having
more self confidence in their ability to take care of themselves,
particularly in familiar surroundings.> He is eating and looks fine
and I have had him for over 2 years now.<The age would seem to indicate
that it's at or approaching sexual maturity.> Is there any chance he
is looking for a mate? It is spring here in Australia.<That's always a
possibility as spawning urges are often triggered by the length of the
daylight hours. It's quite likely that the presence of another, older
Snowflake would be the final factor involved, but if they are like many
other eels the probability of captive rearing is extremely remote due to
their complicated and extended juvenile stages.> Cheers Jess
