Well I have 2 oscar,1 serveurm,1jd,red tail botia and a pleco in the tank. Everyone is swim and no one is fighting. And I think that I have a male and female oscar because they swim with each other and dont fight. But then my jd just sits at the bottom corner of my tank right behind my big bonsai tree and does nothing. When theirs food everyone eats but him. He swims now and then but only around the tree which is on the far right of the tank and he never goes to the left side of the tank or to the top. Is this a good thing or bad? And do you guys think I have a male and female?

ninja, ur rushing into things
u went from a nicely stocked 55, 2 a crowded 55, to a crowded 55 with an oscar
then a 100 w/ 2 oscars and a red botia, to an overstocked 100

Im sad now. Just went to look at my fish and the jd was being pushed by my powerhead. He was struggling for air and had a last stand push and then he pasted. When he was struggling I was trying to help him by reviving him, but he didnt make it. When I firsted put him in the tank he wasnt acting right. He would stay on the corner and had his fin clamped to his side, but evernow and then move to a different spot and had his fins clamped. I feel real sad right now. I dont know if he was sick from the beginning or my water is bad. But I highly doubt that because everyone is eatting and swimming fine.

You better hope that those two oscars are not male and female. If they pair up, everything in that tank is going to die.

Unfortunately there's too many fish in that tank.

A test kit is a MUST...especially in a new tank. The JD could of been sick already and by not acclimating properly could have made him weaker. Also you'd better hope that he didn't introduce disease into your tank or you may end up with other dead or sick fish....sorry to hear he died. First thing I would do is get a test kit which has been recommended on several occasions. Secondly acclimate and and quarantine new fish properly. Lastly if you are going to overstock that tank I would triple the filtration you already have and plan to do several large water changes each month.

SBL is right, I also agree with what the others have said, and if those Oscars are male/female not only will they destroy everything else in the tank but with that size tank you can bet that the female will get pretty beat up is any mating goes on. The Male may harass her to death so be prepared to move her or him. Not to mention you never mentioned that you were getting a 100g TALL tank which is not beneficial for the adult size of the species you are keeping. The tank you have would be more suitable for Discus, Angels or smaller Cichlids. I promise you if you follow advise we are giving you and slow down you will be able to enjoy the hobby much more and will be much more successful.

I would explain to your parents the problems over stocking your tank will cause and polity ask them to take back the other fish and refrain from purchasing anymore. If this is a family project ask one of your parents to join the forum to get more help.

YOU NEED A TEST KIT...your LFS water test are not sufficient. A good test kit here in Canada is $39.99 and that is for a Aquarium Pharmaceuticals Freshwater Master Test Kit. In the US you would be looking at paying $21.89.

I agree, do your own tests dont rely on the LFS to read your water. I have a hard time believing the water is perfect, and water can change real quick esp in a new setup....I am just trying to save you some time and work.

Didn't you say your uncle gave you the tank? Did he keep fish in it before he gave it to you? Maybe he has a test kit sitting around you could swipe?

Get the freshwater master kit from API.

I am not at all positive on this, but I *think* the 6 in 1 kit from petsmart is the same as the API master kit.

As for the tank size, I wish we had asked you for measurements before this all started. That tank you have is an extremely uncommon size. A regular 100g is 18 wide x20 tall x62 long and your tank is 12x26x62. That width is going to cause problems for any fish that normally grows out to about a foot.

Given how uncommon they are, I'm going to guess that ninjastar honestly didn't know the difference, and just got excited about the free tank. I know I'd get all excited about a free 100g tank, tall normal or otherwise.

So right now, I'm not sure what to tell you. I know you're not going to get rid of the Os, but in short order they're going to need a wider tank.

Nevermind that no matter what the tank is still overstocked. Oy.

Well Im putting money away for a bigger tank. Im willing to buy a 500gal tank if need being. But ya Im putting money away for it and if I put away $50 each week which in 4-6 months i will have over 1000 and that would be more than enough to buy a good size tank with a good size filter. And then after that I might convert my previous tank to a satwater tank.
