Educating MFK on the Silver Arowana (REVISED)

  • We are currently upgrading MFK. thanks! -neo
what if aros and other fishes have a different type of vision than ours? and i think they do. i think they haver a lot more sensitive eyesight for light and the way light is manipulated by reflections under water. just a question.....

though i dont really believe in that bare bottom causing drop-eye theory, i cant help but just keep my mouth shut when confronted by people who do. this drop-eye thing has just been a constant nagging concern and really no clear answers. well i hope, some accurate research is done for this in the future....

she doesnt lay them on anything

she drops them and the male scoops them into his mouth for incubation.

throw in another big aro and your inviting trouble.
 
So, how do you really sex aro? Good write by the way del. Bare bottom is not the problem. i have an aro w/o drop eye and i got "almost" a bare bottom tank.
 
Really great post, we have two blacks, a male and female. Here in New England they generally refer to them as Blues though. It would be incredible to me if our two breed. Everyone seems astounded here that we keep them together, but I don't know why. I wonder if there is something we don't know. Feel free to shed some light if you know this. Our Female is 2 feet and our male is a couple inches shy of that. We have found that Krill heightens the salmon colored stripes on their scales to a great deal. Our male will eat pinkies but the female definitely wont. It's almost as if its beneath her dignity to do so. It's really funny. They amaze me all the time. They are such incredible predators. We have an odd house with a loft that looks over the living room where their tank sits. One morning I woke up and came out onto the loft to find them looking up at me! I was about 20 feet away and I could see their huge eyes trained on me and watching every move I made! Sometimes I wonder who is actually in the tank being watched, them or us! (I'm pretty sure they think that we are their pets!)
We named our two Scylla and Charybdis after the two legendary monsters from Greek Mythology. Each lived on opposite sides of a narrow channel. In ancient days they used to say "between Scylla and Charybdis" instead of "Between a rock and a hard place". We bought these two together before they could be sexed, they were young. And it was following the death of our first Black, Akasha. She appeared to have died from a cancerous lump located between the stomach and the intestine. It helped us to the do the necropsy. It let us know we hadn't done anything wrong. She had always been a poor eater. Imagine that, an Arawana that's a poor eater. But what I really need to say here is that these fish really affect you. When she died we both cried for several days. They really have huge personalities. I am so glad Akasha was a part of our lives. And I am doubly glad that I was able to talk my husband into Scylla and Charybdis. He was resistant but I wore him down. Anyway thought you might care to see em. great post on the silvers!

you sex them by the structure of the lower jaw, (at least in the Black) The males lower jaw tends to end higher than the upper jaw so they overlap. The females lower jaw is slightly lower at the end point than the upper jaw. (does that make sense) I wish I could draw it for you. It can be a pretty subtle difference though so if you have a chance to observe a group of them, that helps a lot. If we were talking about humans that need braces...the males would have an underbite and the females would have an overbite.
