no matter how big or how small the shoal of red bellies, you will have casualties either way.
i've kept 6 at a time before as babies, and only 3 made it.
and recently i kept 50 of them as babies, and i've already lost around 6 or so and their only reaching the 2'' mark.
a general rule for red bellies is 20gal per fish, becasue they can reach 12''.
They are in the Tetra family. It is said that they can be kept with P's, but I tried it once and they made it a couple of weeks because they are so fast, but eventually the dissapeared one by one. At night you could hear the P's splashing around chasing the exodons...eventually they caught up. You might get away with it if the tank were large enough to give the exodons LOTS of space to get away, and you kept the P's well fed. More than likely though they will end up being very expensive feeders.
Exodon paradox or bucktooth tetra. grows to around 3" max. My experience from owning this fish is very dissapointing.
I used to have 26 in a 75gallon tank. They pick on each other too much and can easily injure one another. Once injured they cant hardly heal like other fish.
They are somewhat mean fish but too damn fragile.
To make my post short I was down to 0 exodon. Most from dying being injured and others jump out from the back of the tank, the rest the Piranhas ate them.
At $7.00 each, Im still pissed at the money wasted for this junk fish.
I've kept these angry characins once and had bad luck with them. The reason, not a large enough tank and not a big enough school. They can be kept with sucess but only if you pack a lot of them into a big tank. I wouldn't go below 15 of these in atleast a 55g tank but that's just one mans opinion.
I live in Hawaii and have seen some of these for sale lately. I was suprised because I thought they were in the P family and P's are illegal here.
Could I put a shoal in with my Aro?
