Is Compsaraia compsa an old name for Parapteronotus hasemani?

Apparently these larger snouts are to be found in (sexually) mature males; they are used to impress or even to fight other males (afaik!!).

Shane: would love a copy of that publication( is it french?) you attached if there's a way to purchase it and its not too expensive? See my initial post for title and author. It is in Spanish (and English?). And - to my regret - copies of this publication are scarce and (thus?) expensive. There was...

Could you expand a bit more on this one? I can't find any reference to this species - except through Google, which refers back to this thread.
FishBase also doesn't list it, so I'm very curious.

I'm currently looking forward to the arrival of some Auchenipterichthys punctatus in the Netherlands. A real case of "long time, no see", because the first (and last) time I kept this species was in the eighties. Two specimens - which turned out to be a pair - as "stowaways" in a...

Thanks Larry, there nothing wrong with a good start. And you may include the electric eel

Here is a picture of one of my diggers/buriers, Gymnorhamphichthys rondoni. Not the best of pictures - these fish are very fast - , but you may get an impression. This one is feeding and they do so by putting their mouths into the substrate in a chicken-like manner. If things become too tense for wh...

There is not very much information on this group, which is scientifically known as Gymnotiformes. According to Silurus (HH), only one book on them has ever been published (Electric Fishes of the Continental Waters of America, Mago-Leccia, 1994). Googling for images of S-Am Knifefishes results in an ...

How are the Ageneiosus doing atm? Settled in a little? Sorry for not reacting to your Discus story. I know little to nothing about them, but I can imagine getting robbed of their youngsters constantly should disturb them(?). I picked up two Otorongos from Kruseman yesterday. They had squeezed themse...

Sadly, I found one of my otorongos dead last night - no idea why, was small but chunky, no obvious damage but must have been dead less than a day. That's sad and strange, especially because there's nothing to be seen which could explain its death.....Hope your other specimens will remain fine. I wi...

Hi Martin, They look good! This is a very nice species, especially when younger. Once old - like mine - they start to look like some kind of Stealth airplane, by which I mean that the fish's body parts seem out of proportion (large, flat head, skinny body) and don't seem to match anymore. Your tetra...

Hey Martin, My trio did well on live feeders. The pair died a few years ago and currently I only keep the remaining single male. I have wondered several times why it is still alive, because it looks like a swimming head. Mind you, this fish is about 15 years old. Yet, when possible, it will grab an ...

I still don't see the point in splitting Tatia and Centromochlus . Together they are a well diagnosed group with relatively few species. The two genera can only be told apart by experienced systematists with morphometrics and cleared and stained material to hand. Heck, even Vari & Ferraris (201...

It does rather, but the dark distal margin to the caudal is pretty distinctive in this fish though. Maybe part of the same species group? I'm a bit at a loss as to what a dark distal margin is, but if it has anything to do with a tail pattern (probably not....) it could also be Centromochlus macrac...

Determination seems correct imo.

Absolutely awesome, mr. Collins, you made my day!!
Keep up the good work and share some more please.
Btw: any sightings of gymnotids?

Is it the peace and quiet in the tank now that all characins have gone? Is it the effect of catappa leaves (tanned water and a natural environment)? Is it the company of guppys and their pheromones (not sure if other species should react to that, though)? Is it just the time of year? Or is it a comb...

As I'm unable to see the difference(-s) between T. brevis and T. venezuelae, I prefer to think this is T. brevis. Kept these on two separate occasions as individual and both times found them as bycatch in a shipment of Corydoras pygmaeus. Both brevis did well for some time and then suddenly simply d...

Have a closer look at the family.
You can ignore the genera and

I'm sure must have juvies too, but the recent image update of a Trachycorystes juvenile is imho by no means a Trachycorystes but some Tatia species.
It concerns the latest picture addition, number 13.

I can't be very specific, but looking at your picture this one definitely sits in the . Click this link and have a look.

it was imported from Brazil. Given that fact, could it not be a yet unknown Pimelodidae or Heptapteridae? As an example from another genus (and another continent): I have seen Chrysichthys species with very large eyes, despite the fact that most members of that genus have much smaller eyes. I doubt...

Google on this: "rooibos tea aquarium" and enjoy reading.

Or - much easier - use Catappa leaves: nice tan/colour as well, good for your fishes too and additionally very decorative.

Shouldn't this be sitting in the pleco department?

sema2.jpg A lot can happen in about one and a half years. Yesterday I had to say goodbye to my Semaprochilodus and when viewing the picture half way the previous page (can't make it work through a quote, sorry)it struck me that all fishes on it have vanished from my tank by now (except for the Agen...

And thus happened. The Hoplos are out and I was able to obtain a very nice knife fish species to take their place. I now keep three specimens of Gymnorhamphichthys rondoni and they are able to bury themselves in a sandy bottom completely. Sold as M-(edium)sized I expected fishes of about 5 to 7 cms,...

(Mostly)@James: Thanks again for your reaction. I was not able to visit any of the shops you mentioned. Saw one shop in Maidstone, which looked promising from the outside, but was closed at the time (Sunday afternoon, around 6 PM). Most of the garden centers we have visited, have a fish department. ...

My Otorongos are definitely on their way back to improved health or - if you like - getting to some food. It amazes me that these tiny fishes were able to last so long on an absolute minimum, due to a lot of bulging tank mates, such as the Chanallabes sp. - which role has greedily been taking over b...

Good spot, but how did you get there? I am unable to find a Centromochlinae page nor am I able to find the Auchenipterinae page without your link.

Yes it is.
From this picture I cannot make out which species it is.
