A week back, i introduced 2 Black Ghosh Knife fish into my tank. Moments after introducing some of the primitive natives in my tank (Black Molly(2), Variatus Platy(2) and Gold Gourami (2)), started distrubing the Ghosts by pricking into their tails and all.. Except my Gold fish(2), and Dani Sonii(4), all seem to be quiet unhappy about the Ghosts being introduced. This phenemenon continued for about 20 minutues, and when I realised that its not going to stop, i fed the fishes, and then everything was normal..they started behaving as if nothing has happened...That night crossed and my ghosts were fine.. I have only two hiding places in my tank and both the Ghosts have occupied that.. Just after a day, I introduced a Siamese fighter (Betta Splendon).. (i generally do not introduce fish this fast.. but this was on order, and colour of the fish was spelndid shades of blue everywhere...if I would not have taken it, somebody else would...)..The fighter was not attacked by anybody and I kept a watch for 2 - 3 hours during evening and everything was fine.... From the next day morning onwards... THE FIGHTER JUST VANISHED IN AIR.. I had searched all corners of the tank, thought it was sharing the hiding place with one of the Ghost but three days have passed by... there is no sigh of the fighter... I have no explanations.. I have mentioned all the population of the tank above and in addition to that I have two small crocodile fish... My suspicion is towards the 2 black ghosts I have.. but is this common a black ghost eating up a fighter...? In short my beautiful fighter has vanished and I am looking for an explanation.. if someone can help? nimo 2008-06-27 http://forum.aqua-fish.net/?topic=my-siamese-fighter-has-vanished-#2 the ghost fish are carnivorous but I don't think to the extent of killing your fighter.You said it was on order, did you check that it had been quarantined before the supplier sold it to you. Is there a lot of water flow in your tank sometimes fish will hide for a few days when first introduced and its surprising the spaces that they can get into. mickey 2008-06-27 http://forum.aqua-fish.net/?topic=my-siamese-fighter-has-vanished-#3 Yes it was kept alone in a jar... you know the funny thing is the ghosts which I had bought, was sharing the same tank with Clown Loach, Dani Sonii and Discuss (4) of them all small, for over 2 months.. Nothing happened to any of them.... So, now it is hard for me to believe that they did not harm the slow, lazy aquarium king Disucuss for two months and moment they were introduced to my tank.. they started eating away fishes.. but still 3 rd day --- no sign of the fighter... thanks for your help anyway.. let me know, if something else comes to your mind nimo 2008-06-28 http://forum.aqua-fish.net/?topic=my-siamese-fighter-has-vanished-#4 Hey mickey.. you were right.. he was hiding inside the undergravel of the tank.. for past 1 week. He came out last afternoon.. and now he is fine.. swimming all across... nimo 2008-07-07 http://forum.aqua-fish.net/?topic=my-siamese-fighter-has-vanished-#5 glad the fish is o.k. just watch how much water flow is coming out of the filter,fighters like a calm tank as do the discus. I am running 2 externals on my tank but I have turned the outlets right down so that they are jut trickling back into the tank via spraybars mickey 2008-07-07
