Lets see who know their fish compatibility...?

Question

Alright I have a 125 gallon tank and a bunch of fish most about 3" - 4" long right now.
1 Rubber Lip Pleco
2 Chinese Algae Eaters
1 Bichir
1 Peacock Eel
2 Knife Fish
3 Silver Tipped Catfish
3 Spotted Pictus Catfish
5 Bala Sharks
2 Cory Catfish
1 Tetra Barb
1 Zebra Danio
9 Guppies

I am planning on the guppies being food for some in a couple months, but what do you thin about the rest? (bichir, sharks, catfish, knife fish, peacock eel) Will they be fine?

Answer 1

You have a couple of potential problems that come to mind. First 2 knife fish, not a good idea as they use electrical current to navigate and two will confuse each other. They are also rather territorial. 2 Chinese algae eaters, they are also territorial and very aggressive as they get larger and older so that's a problem. Even one of those nasty beasts is a problem IMO. The 3 Silver tipped catfish will out grow the tank within a couple of years and call anything else in there lunch in the process most likely. You have tons of bottom fish, but other than the food and the 5 bala sharks, nothing much swimming the middle or upper waters. All of those bottom fish will fight over territories. The 5 balas would almost be enough for the tank before too long as they come close to adult size, but they would still leave room for a few smaller bottom dwellers, like the Peacock eel, but that will probably be lunch for the Bichir or a silver tip before the balas get that large anyway. Who knows, depending on starting size and how fast each fish grows, the silver tipped catfish might do away with the balas before they get too large anyway. Who really knows what exact scenario would play out, but one thing is certain, after about 6 months very few of those fish will be left.

You have way too much fish and way too many predators listed for that to work for any length of time. Whatever is left after the growing out phase will constantly fight.

Answer 2

They are both compatible. The Coral Beauty is a very fast fish and once acclimatated it will just out run the yellow tang. Yellow Tangs prefer more open spaces to swim, and since right now the Coral beauty does not know your tank's landscape very well, it is being made into an easy target. I would suggest the following: 1. Turn off lights and let the fish settle in. 2. Try covering the tank with a blanket, again to ensure absolute blackout. Incase this does not work out: 3. Change the rock-work. Again turn off the lights for the day. (this will change all your fish's usual positions)

Answer 3

I agree with everything that Magicman said, and I'm going to add that tetra's are schooling fish -- not matter what kind of tetra you have. The Zebra Danio can become nippy towards others is there isn't other Danios in the tank to keep him/her entertained. The bala sharks will outgrow the tank in no time and the rubber lipped pleco needs to be put in a tank with less aggressive fish. Cory cats are schooling fish too -- two of them aren't a school.
Like I said, I have to fully agree with magicman. He hit it on the head when he said that you have entirely too many bottom feeders and aggressive fish in one tank together.

Answer 4

Very poor choices,a race to see whose mouth will get large enough fast enough to eat the tank-mates.Research first,buy fish food later.

Answer 5

well the guppies and zebra danios are already going to be food. as for the rest, that'll be fine.
