Good info until you said the Orinoco Altum is a cross/tank bred species. The Orinoco Altum comes from the Orinoco river basin......... That breed is not a man made creation that is a wild varation of fish.....

I have a question, anyone please help me out... I have a 40 gallon tank with 2 gourami 4-5' each, 1 angel 5' and a rainbow shark 5-6'. I know my gourami eat and so does the rainbow shark, my angel doesn't go after flakes or freeze dried food or blood worms, however I provide about 10 to 16 fry a week and they are disappearing. Who can be eating these guys, I never see the shark or gourami chase or show interest in the fry, but the angel eyes them and stalks. Could he be feeding on them, I really don't know who is feeding on them and I do hope its my 'black marbled angel' cause he really hasn't been eating anything yet he is healthy and alive and active.

    Because your angelfish is healthy, active and lively it sounds like it is just fine so is probably eating something. Hard to say who is eating the fry without actually seeing them get eaten.

I have had my Altums for almost a year know. I got 8 altums. They eat and grow nicely. The largest is about 200mm high now. The tank is 570 liters. It will be intresting to see if the tank is to small when they paire out. The largest Altum has started to become territorial. The terrjtory is about 1/3 of the tank. I will test with more roots and plants to see if the teritory shrinks. Anyone have Experians of Altum teritories?

    Well that is exciting! We got our Altum from a wholesaler, gosh back in the late 90's, and it was very hardy. It had it's own tank initially, but didn't need any medication as it acclimated well. We then moved it into a fairly large community tank and it continued to do just awesome.

This pretty fish has grown immensely since we first got it, about 8 years ago, and it has developed much more red, especially on its head!

Are Rams compatible with Heckel Discus, Altum (wild) Angelfish, and Black Ghost Knifefish? How about with Silver Dollars?

    The Knifefish needs a minimum of a 100 gallon tank on his own. They are beautiful but they get huge and he will most likely eat the others.

    The angel fish isn't recommended but you may try with a knife fish all depends on you tank size to oh and for the discus. Alot of people may tell you to keep them in a single species tank and they need different water phlevels in their tank.

I have 2 angel fish. They are both the same size. They hang around together all the time. Now the black one is chasing the other one all the time. It's in the corner all the time. I have a 30 gallon tank. Should I get a couple more angels? Don't know why it started picking on it. Should I just take one out and the black one can be by itself? Don't know what to do.

    Angelfish become aggressive towards each other as they mature. They establishing a pecking order and the tank needs to be large enough for each to have its own territory. These fish are best kept alone, as a bonded pair, or in a larger group of 4 or more. There's no way to tell whether the aggression will escalate or not, but keep a close eye on them. If injuries occur, then they will need to be separated. Your tank really isn't large enough to house a group.

I have an angel fish and tetra in a 35 gallon tank. About 6-12 months ago they stopped eating and didn't swim around as much as usual. I changed the filter and some of the water and they were fine after that. This time it isn't working; they started to swim around normally for one day (still didn't eat) and then it was back to quiet. There was no other signs of disease. I just moved the fish into a smaller tank in another room so I can completely clean out the big tank and when I did so, I noticed what looks like a small film in its eyes that I didn't see before, although I had checked the fish over carefully. Don't know if it's a new symptom, whether it's supposed to be there, or whether I just couldn't see it in the other room. I'm not sure how to treat this fish.

    Oh yes, I forgot to add that I had the water tested at a local pet shop. The PH seemed a little high and I lowered it, following the instructions of the pet shop exactly, but it didn't make any difference.
