If this should be somewhere else, please move.

Now, plans for a monster tank (Or monster tanks) have flown over my head like a flock of birds.

Likewise, I'd like my first tank to have it's stocking primarily from the Super Order Osteoglossomorpha.

That said, I've got my bases on the Osteoglossoidei, Notopteroidei, and Heterodontidei, suborders.

Arapaima Gigas is out of the question as I'm considering an aquarium and not a bonytongue pond.

Fish from the order Hiodontiformes are out of the question as well due to the need of colder temps and may only work if I ever tried with Koi/small Sturgeon, aside from the fact that I don't know where I can find a supplier and whether he could sell me live fingerlings or smoked fillets :ROFL:.

Here is where I have a problem at: the suborder Mormyroidei, the Mormyrids. The only species I really have any knowledge of are the ones represented in Gina Sandford's "An Illustrated Encyclopedia of Aquarium Fish". Sadly, all but one reach a size range of 4-10 inches and have very small mouths and the only one that may work only reaches around 17 inches and is an elephantnose. Which means a small mouth again, though bigger due to it's larger size, but unsure if it could/would take fish as food. The species represented are (Common names and size statistics were taken from the said book authored by Gina Sandford):

Gnathonemus Petersii- Peter's Elephantnose (9 inches)
Gnathonemus Schilthuisae- Schilthuis' Elephantnose (4 inches)
Gnathonemus Tamandua (17 inches)
Marcusenius Brachyistius (7 inches)
Marcusenius Longianalis- Slender Elephantnose (6 inches)
Marcusenius Macrolepidotus- Large-Scaled Elephantnose (10 inches)
Petrocephalus Bovei- (4 1/2 inches)

My question: Can anyone tell me of a well sized Mormyrid (IE a foot and above) that has a mouth big enough to eat sinking pellets/feeder fish? I know some may suggest going for an Aba Aba, but I don't want to try due to reports of it being one of THE most aggressive knives. So if anyone could direct me to a mormyrid with those characteristics I pointed out, it would be highly appreciated.
 
arowana knife - Papyrocranus aferis + as stated cornish jack - Mormyrops anguilloide... both will get aggresive tho cornish are very shy in day but monsters at nite. both get a reasonable size too...

black ghost knifes
clown knifes
royal clown knifes
 
I already know about the Clown/Featherback Knives already. And between the Afer and the Cornish Jack, the Afer would be more suited to tank life.

Also, BGKs are not Bony Tongues. Though, I would probably consider some SA Knives.

Anyone else in the forum who could help me decide on some other mormyrid species?

I'm basically looking for anything with good size and mass would not have trouble eating pellets or feeder fish.
 
The freshwater butterfly fish are also bonytongues but they dont grow to a large size.
 
Campylomormyrus neuminus 65cm, Mormyrops Longilostris 70+cm, and Mormyrops Kanume 70+cm get pretty big

but I think those that he said are not available in the Philippines

That's not what I'm asking. I'll take care of gaining the Mormyrids after I'm done with college and starting the tank.

Right now, I'd just like to know if they would be able to eat what I had stated in my previous posts.
