So I bought a 75 gallon 4 foot long tank the other day and I'm not too sure what I want to do with it fish wise I have another small tank with columbian sharks and convicts in it right now I'm not sure I want either in this big tank at this point in time as it may limit my options the convicts are very cheap and fairly aggressive and one of my 2 sharks seems weak I know they need to be in a brackish or saltwater tank eventually from what I read and I'm not sure i am prepared to do that with my new big tank(to me maybe not to some of you) but I'm not sure what I want I'd like some aggressive fish but I'd like to have a couple different types I have ideas in my head such as arowanas and peacock bass, or piranhas and Oscars, or an emporer id shark I had one before and can easily get my hands on more but I woke up one morning and it was dead so i wasn't too sure what to think it might be a more difficult fish to keep,maybe a FW barracuda or shovelnose catfish or even something native like a bass ...this tank is in the middle of the room has no background but some real plants, rocks and what not blue gravel bottom I would prefer something that wouldn't outgrow the tank too quick and if they were attractive or colorful fish i wouldn't be a terrible thing

Only requirements
Must be a fish that will eat other fish but be able to live with its roommates
must be able to spend a good few years in my 75 gallon 4 foot long tank
must be a fairly easy to purchase fish
must be able to live healthy in fresh water permanently
 
ya its nice gravel i bought it cuz they were clearing it out and it was 1/2 price ill post more pictures once i get all my stuff up and running again but all my electronics have those blue glowing lights that are the same color as that its gonna look sick at night with the lights off just lighting up the room with a blue glow...and just for jokes i do the ole xmas tree in the same color blue lights
 
How about a Polypterus? Ornate, Albino Senegal, Congicus, Retropinnis, Endlicheri....
 
:iagree: Several of the Polypterus species would be a great choice for the bottom dweller picks, upper jaw species in particular. I'd go for a nice delhezi; not overly large, very attractive,not too pricey & fairly active for a bichir. Also will munch smaller fish if given the chance :D

Some of the lower jaw species may be a bit crammy for a 75......

O
 
I was looking at some of those Polypterus actually I really like those theyre about 40 bucks each around here for one thats like 3 inches long what can i have living with that? it wouldnt eat a lobster would it??
 
You should put the columbian sharks you currently have in the tank, they need the space and since you already have them you are obliged to give them the space they need to grow and thrive properly in, like your new 75gallon tank- its the best thing you can do as a responsable fishkeeper, instead of getting more new fish knowing that you should be sorting out the current columbian sharks proplem.

Anyway, thats my advice :) - if you don't want to look after the sharks, then give them to someone who does want to look after them properly "nods" .
 
I know I'd like to keep them but I made the mistake of not doing my research before i got them and no one told me they had to go to a saltwater or brackish tank I have a few buddies that have tanks and will probably end up giving them to them or i may go back to the pet store where I got them and be like you never told me theyde have to go to salt water i bought an id shark with them that is freshwater ud think theyed know enough to tell me they couldnt coexist in the same tank when they get bigger but they didn't i got them so i could put them in with the other shark cuz they told me they'd get along i have a buddy that has one too i might give it too him cuz he's gonna have to do it with his anyway ill see if the pet store will let me trade them towards something else I didn't buy the tank so i could adapt it for two 8 dollar fish i just need to make sure I do my research before I buy something again cuz im prolly gonna be spending a lot more then 16 bucks next time

i'd consider trying the brackish or saltwater thing but ive heard so many horror stories i figured i'd be more responsible of me to get fish i can provide the proper care for and give the columbians away
