    What size is the angel? And can you attach a pic of your setup?

    Maybe they're picking at the angel because they can tell its weak, but that's not something I would have expected.

    His tail was messed up when i got him but it seems like part broke off today. Tank is cycled and nitrates at about 5 ppm.

    Very beautiful angel and about your cardinals....maybe you should rehome a few and get another fish thats bigger like a DG. Ive learned that if there is only 1 big fish in the tank that's bigger thwn them then they will feel over powered.

    Like what I am saying is that if there is nothing in the tank that will be the boss then they think they r the boss so they pick on the ones who are lesser than them....try rehoming some neons and get a bigger fish like what I said a DG or something else simular in size and aggression as the angel

    Definitely do not want a DG bc of he high prevalence of iridovirus. Also cant rehome the cardinals. Would have to rehome the angel :( i hope that it wont have to come to that

    Hm ok lol yeah sadly you will most likely have to rehome the angel :'(

    I just feel like it is not normal for the tetras to be the agressor

    When I had rummy's they were scared to death of everything that happened around and in my tank.

    I have only seen this happening since the ich developed on the angel.

    I would treat the angel for its ich and keep it in the other tank. Make sure that he is fully healed and well fed before he goes back into the other main tank

    If you do have ich then every fish in the tank has been exposed and will need to be treated. Are you able to identify the cardinal that is nipping? If so you could rehome that one fish. It may be that the diseased tissue has a smell that is attracting the cardinal. Just thinking out loud. Alison

    I have been treating the whole tank for about 14 days now. I thought it was safe to move the angel in a couple days ago because there were no more symptoms and my QT tank for some reason was not processing nitrites. So i thought the best plan was to move the angel into the main tank thinking that it would be best for the angel to be exposed to the tail end of ich instead of the tail end of a cycling tank (I thought my QT tank would instant cycle with some filter media that had been running in my main tank for 2 weeks or more . . . now I know that I need to do a trial run with ammonia on my QT tank before putting anything in it).

    Unfortunately, it is more than one cardinal that has been doing it and I cannot tell which ones because they dart off so quickly. The angel came to me with really bad fins, and there was some blood specks in caudal fin so I figured that piece would eventually fall off.

    Also, my cardinals have been eating mysis shrimp that I put in the tank for my angel and ram. I was surprised that the shrimp interested them. You could be onto something with the rotting smell attracting the cardinals.

    How long does it normally take the angel fins to heal?
  16. BamBamSorg Well Known Member Member

    My fish healed in a month or so. It will take longer since your fish are nipping at him. I recommend that you love him to a different tank for a month or more. It will heal better and not be bothered by the tetras. And for the tetras......Im just thinking aloud but maybe u could try to find a pic of the same angelfish and tape the picture to the side of the wall of the tank. The tetras should try to go after it and if they do try to nip. Then eventually they could learn that by going after the angel there is not benefit or food near or on the angel. Im just guessing but it could work. It could also help the tetras get used to the angel better and leave it alone.

    With really clean water meaning a lot of water changes than they should heal rather quickly. Shrimp of any kind seem to be a universal treat for just about any fish, the same with thawed frozen bloodworms. Even my ember tetras slurp them up and the same with brine shrimp, and they are tiny little fish. the males are only 1/2 inch long. Alison ...;)

    Well this morning the angel has a cottony fuzz looking growth on injured caudal fin. I wonder if it is time to QT and treat with meds for secondary bacterial or fungal infection? Ugh...
  19. BamBamSorg Well Known Member Member

    Man your angel is not having his day. Yes I would keep him the QT and treat him for what ever you think needs to be treated :)

    Sounds like a secondary fungal infection from the wound. Tolak might be able to tell you what to use to treat it. He breeds and raises angels and is very knowledgeable. Alison
