Any Opinions?

[Hoyo12]

I was thinking of putting the Glass Knife in the 60-Gallon, but would like some other opinions first.
Inside the 60Gallon
1x BGK
1x Albino Red Oscar
1x NN Gar
1x African Butterfly fish
1x Red Wolf fish
1x Grass Cutter Catfish
1x Senegal Bichir
1x Rope Eel/fish
1x Raphael Catfish
2x Eclipse Catfish
1x Channel Catfish
1x Marbled Headstander
1x Leopard Pleco
1x Bluegill
and a Tire Track Eel.
Now, I do know that two electric Knife fish will not get along, however I have put the BGK in with the Glass Knife in the 10-Gallon, and haven't had any signs of aggression yet from either of the fish. The Glass Knife is a little cautious, but that may be just because the BGK is larger than he is. Now, I will be getting some more rock later on for a few of my tanks (Give some more hiding spots in the 60-Gallon, catfish need it, to crowded on the other side of the tank in the rocks) so once I get that ready the Glass Knife should have more places to hide, but like I said, I would like some opinions first.

Your tank seems quite full. It's not really a problem of putting 2 electric fish together, but just a matter of space and territory. BGK will eventually start getting aggressive and Glass Knives are usually pretty timid and also do well in groups.

 

[Hoyo12]

The tank is a bit full, but when the Catfish and other nocturnal fish hide and sleep in the rocks all day and partly through the night, it seems like its almost empty, lol.
So I guess in other words, its worth a try. Alright, I'll probably give it a try, and if things don't work out I'll take the Glass Knife back out. (Have to get some more rocks first)

I did look into the tank at the LFS where I purchased the Glass Knife. There were two, but they were on opposite sides of the tank, and both has bitten tails (Mine has his growing back right now). There was nothing else in the tank, and nothing else on the tank showing there was something else with them before. I would have loved to get both of them, but they were $15 each, I had a small amount of $20 when I entered the Store.

Your fish collection looks like is a recipe for a disaster. The oscar will out grow the other fish and will eat the smaller smaller slender fish. The senegal might death roll the marble headstander and the african butterfly fish. You glass knife might get eaten by you soon to be larger fish. The channel catfish will grow to big and will eat anything that it can fit into it's mouth.
Leopard pleco will start sucking on the ropefish and the ropefish will stress out to death or get attack by bacterial infection. It might not happen now or you have not seen ity yet but it will happen soon.
You should do some research and look for the max size and growth rate.

 

[Hoyo12]

lol, I do know sizes of the fish that will soon be, and I have had this setup for the past 5 months (Going to be 6). No issues. The Rope fish is full grown, and it sleeps during the day under a rock with the Leopard Pleco. No one bothers the Headstander, which surprises me. (Plus he's a fin nipper, so everyone tries to avoid him) I do know the future size of the Channel Catfish, and he will be upgraded to a larger tank once he gets larger. (Along with the Eclipse Catfish) The Senegal Bichir is a wuss, afraid of everyone in the tank. (Currently 5 inches) No one notices the African Butterfly fish in the tank. I do my research constantly.
Do not say anything, unless you have tried it yourself. Now, I understand, things may not work out in the long run, and if that happens, things will be moved to different or larger tanks. (I am curently looking for another 55-Gallon so I can move some fish into it)
I have moved the Glass Knife into the tank with no issues so far. I am keeping a an eye on the tank though. (Probably will until I decide to head off to bed, then again, my bed is right by the 60-Gallon..)

Then, instead of adding another nocturnal fish, you should get a diurnal fish. My tank has the same problem, lol.

Anyway, I just bought a glass knifefish yesterday and so far it's been pretty timid. I wouldn't keep it with anything with the capacity of being aggressive if you didn't keep it in groups.

 

[midnightCK]

u did ask for opinions

do the fish always seem to have minor fight marks? might as well get another tank soon since there is some odd loners in there lol. and its only 55 u said right ?

im sure the fish will live for now, but you are sorta stressing out some of those fish
already in some ways.

maybe grab both the glass knifes they do school up for safety. the bgk is gonna defend his home either way thats for sure. take a pic sounds like a fun tank to watch.

I have owned everything in that tank, and had hundreds more of each species at the shop. The tank as it currently is will not work in the long run, but as long as you're planning on moving out the big mean stuff as it outgrows everything else, it should be fine.

I am curently looking for another 55-Gallon so I can move some fish into it

Why are you looking for another 55 though? That's too small for the Oscar and channel cat. I'd go for a 75 at least. I'd also split 'em up like this...

1x BGK
1x NN Gar
1x African Butterfly fish
1x Grass Cutter Catfish
1x Rope Eel/fish
1x Marbled Headstander
1x Leopard Pleco

1x Albino Red Oscar
1x Red Wolf fish
1x Senegal Bichir
2x Eclipse Catfish
1x Channel Catfish
1x Bluegill
1x Raphael Catfish

Back on topic, I would worry more about the glass knives getting eaten by the oscars, channel, senegal, etc as they grow...the BGK will probably leave them alone as long as you have a bunch of decor (which, from the pics of your tank, you do).

Heres my 2 cents- leopard plec (assuming you mean gibby) is a very clumsy fish and when full grown it will unwittingly knock stuff over. Be careful to stack rocks and wood so they wont fall easily.
