African Brown Knifefish. Electrogenic fishes, comp.
1/30/07
Hi!
About 2 years ago I purchased an African Brown Knifefish
<... is this an Apteronotus species? S. American? Or Xenomystus? Or?>
and an Elephantnose fish (Fishie and Ellie, respectively). 3 months ago I had to
go out of town, so my sister took care of my fish for me. Kind of.
<Oh oh>
When I got back I discovered the water quality was awful. I managed to fix the
water, but Ellie still passed away. I want to get another elephant nose but I've
since read that these 2 types of fish tend to hate each other. Is this true?
<Mmm... depends on what species the former is... but in general, a qualified yes
here... Electrogenic species of fishes are best not mixed in small
volumes/aquariums>
These two always would play together and even slept in the same little pot,
despite have numerous places to sleep separately. Should I scratch the
Elephantnose plan and just get a different type of fish?
<Mmm, up to you... but I would be prepared to move the newcomer if there was
obvious agonistic behavior>
I'd be devastated if anything happened to Fishie. The tank is 55 gallons and is
being upgraded to 95 in June, if this makes a difference.
<Does... the larger the "world" the more likely they... and other species will
get along>
Thanks so much,
Amanda

Mixing Apteronotids and Mormyrids... not advised 6/3/06
Hello,
I recently sent an email to you guys in relation to keeping a freshwater
dolphin in a 70 gallon planted discus aquarium. I received a reply of yes but
forgot to add that I have a 15cm black ghost knife. I am aware that the ghost
has a form of electrical field and was wondering if his and the freshwater
dolphin will fight????
<Too likely, yes>
I would also like any opinions on whether its possible to house 2 black ghost
knives together? I would buy 2 smaller ones of the same size and house them in a
large tank with plenty of logs and hiding places) Have you ever heard of anyone
doing this successfully?
<Yes... in very large systems of consistent low pH, alkalinity...>
I just love this fish so much that I would have 20 of them if I could!!!!! One
more thing, how long will it take my black ghost to reach adult length.
<A few years>
thank for your time!

Freshwater fish electro-sense question
I recently bought an elephant fish. today my
girlfriend surprised me with a black ghost knife. they
are both about 3in and are in a 34 gallon tank with
separate very good hiding spots. will there
'electro-senses' clash?
< There have been some studies on these electromagnetic fields generated by
these fish but not much in the popular aquarium literature. But I am sure that
they are aware of each other.>
also how sensitive are they to
salt?
< These fish come from clean warm acidic water and have become very sensitive to
salt.-Chuck>
I use a little less then the recommended dose of
aquarium salt(1tbsp per 5 gallon). tank also includes
6 glass cats and a blue lobster.
thanks for your time.

How many
types of fish produce appreciable amounts of electricity?
<All told about 11 families, a few hundred species... are strongly and
weakly electrogenic. Bob Fenner>
