Hi i am new to this thread and i was wondering if you could help me with my tank... I have a 75 Gallon Tank with a SMALL Arowana x1, SMALL BGK x2, SMALL Fire Eel x 1, SMALL Hi-Fin Plecostomus x1. I understand that the Arowana will get massive and in the wild they get to 6 feet. I also understand that most of the fish will get extremely large... (I plan on getting a LARGE pond). Also i am NOT new to aquariums i am just new to large fish like these i used to own a 29 gallon aquarium before i upgraded and on a different forum i was a known to have good advice but there nobody knew anything about fish that get bigger than 12"... anyways back to my question. My question is what are the chances that these fish are going to kill each other when they get older and how to teach the fish to eat out of my hand.

In extremely spacious surroundings your fish are compatible.
You will probably need a tank with a foot print of at least 8 foot long and 3 to 4 feet wide to house them fairly.
Even as juveniles,those fish wont do well together in a 75 for long. I would upgrade quick or change your plans.
 
You understand? Aro gets 6ft? 2 BGK in a 75? Are you digging the pond right now? Do the fish a favor and return them. Get some tetras and guppies. Get fish for the tank you have right now, not the planned upgrade you think your lawn mowing money will afford you 3 years from now.
 
Hi, a tropical pond is far more effort than you may think, you can't just dig a pond and chuck fish in there.

Your stock will outgrow the tank before your plans for the pond are done so I suggest you return the fish to the store as soon as you can.

The black ghost knives may get extremely territorial with each other, it can happen.

I'd recommend you return the fish and get something that can fit your tank for life
 
thanks, i will see what i want to know but here is another question... how big will they get in a year? and how much would it cost to buy all the supplies for a pond big enough? i understand i would need like 10 heaters.

Those fish could easily grow an inch a month in proper conditions.

For a pond you need a hole, dug out and big enough with a proper liner, filtration and a pond heater with a thermostat and sufficient current. You're looking at a few hundred dollars bud

Welcome to MFK :)

The members are very experienced and have given sound advice. I personally had a baby Silver Aro in a 29 gallon after about a month had to move him into a 55 and into a 180 gallon after 2 months. Aro's grow extremely fast and you will wind up with enormous problem's and frustration if you don't take corrective action. We are absolutely not here to bash but only to help. :)
 
could you guys please give me a group of links so that i can just go to links and buy the stuff and assemble it myself? i will dig the hole... Thanks:)

I believe that you might think building a pond is much simpler than it is. I don't know where you live. If you own 200 acre ranch in Montana, then most of the stuff below doesn't apply to you. (Of course, none of those fish will survive a Montana winter, but that's another story.....)



1) Many areas do not allow ponds due to residential areas having zoning regulations. (E.g., where I lived in Illinois, the county told me I would not be allowed to build a pool, above or below ground, or even add a large concrete patio because of rain run-off needs.) Those that do allow a pond, will have specific requirements on how it's built, how deep, materials, etc., to get approval before the pond is built.

2) Once you have the pond, you will then have what is called "an attractive nuisance." A pond causes children to want to enter yards and play with and in the pond. So, you will need to add a large fence that can't be seen through. Otherwise, you may risk going to jail over an involuntary manslaughter charge, (e.g., if a child gets in the pond and drowns.) Worse still, now that we have told you this, if it happens, you may face a voluntary manslaughter child due to negligence.

3) If you pond leaks, and well, some ponds do leak, the water will enter the water table. This may be a violation, and depending on what you put in the pond, that may open you up to lawsuits.

4) None of this even addresses whether or not you can build a pond. Some land is unsuitable to use.
