Predator Tank Questions

  • We are currently upgrading MFK. thanks! -neo
We have a teacup stingray, Jaguar Cichlid, Peacock Bass, Fire Eel, Black up-side down catfish, and an Arowana.

ehhh I feel like that tanks gonna have a few aggression issues at some point...not being rude just don't want to see any of the fish hurt or stressed.

I'd stick with a sand substrate and medium river rocks.

Uh...I certainly hope you don't think you can keep half of those in an 18" wide tank. I would lose the stingray, peacock bass, and arowana, possibly even the fire eel all get way too big for the 125. On the other thread people gave you some viable combos. Either way with most of the fish you could really use any rock that is not soluble. Also stay away from sharp rocks that fish could harm themselves if they would make a sudden movement in the tank.
 
Get rid of the PBass, ray, Aro, and the eel. You might just have luck with a jag and an Eupterus but most likely just the jaguar would remain due to territorial aggression. Has the tank already been cycled?
 
Yep, I did suggest 1 Jaguar for him in other thread, not sure how he came up with all that fishes :D (i didn't follow the other thread)
 
This is just a school project. Our teacher takes care of fish and has a lot of his own. When summer break comes around he'll take over for us until the next school year when most of us will be taking his class again for the fish. We have also already looked at how big the fish get. Once they get too big for the tank we will give them to someone willing to take them.
 
Have you guys explored treating your ray for parasites? I am assuming you bought a retic which is most likely going to be carrying parasites... I also don't see an form of dithers to break up any aggression? Also they seems like you are going to be having a high bio load and I'm curious if your filtration will be able to handle this stock because if not ammonia will also be an issue at some point...

what is the project, Just curious? I understand you think once they get big enough that you'll just find them a new home. Thats much harder than you would think. IMO you shouldn't just buy fish and ignore there requirements and worry about the issues down the road. I cant speak for some of the fish you are planning on getting but I personally have a Silver arowana. Its grown to 10 inches in 8 months. These fish get big fast!
 
The project has two different parts. We have half the class doing a saltwater tank, while the other half is doing freshwater. Our job is to pick a tank that fits into the given area that our teacher has already discussed with someone else, pick the fish we want in it, figure out the filter and media, what kind of lights we want, the substrate, the decor, and all the supplies/food they will need. Those are the categories he has our paper set up. After we figure that out we take it to the board to be approved. Once it gets approved and the room is done and everything we ordered has come in we get to set up the tanks and run them. We are still looking up the temperature each fish needs and everything like that. A lot of the people don't know what to do with tanks like this, but where trying. We are suppose to work on this for environmental science for the rest of the school year.
 
It really probably is better for a grade that way, but he was gonna do something like this anyway so he just had one class out of all the environmental sciences to do it.
