Hello,

I have had my tank up for almost 2 months now. At first I bought all the tetra that I wanted in the tank: 7 blood fin, 6 Serpae, and 6 hatchett tetra. Then I decided to add 4 angelfish to the mix. They are about 4-6 inches in length from top end of fin to bottom of bottom fin.

Everything was going fine, for about 2 weeks now, until today. The angelfish are sitting up behind my powerhead and not going anywhere, I looked at one of my angelfish and the fins look a bit rugged, like theres been nipping. I saw the same fish swim out from behind the powerhead and noticed one of the bloodfin tetra messing with it for a second, but it didnt look that aggressive, but thats all I have actually seen.

I didnt think keeping these 2 fish together would be a problem, and it wasnt until today, whats going on? What should I do?

Thanks
 
Are all the angel's behind the powerhead? At that size angels will start to breed, If you have a pair they will attack the other angels. I did have 6 angels in my 55 but once a pair formed i had to get rid of the others because they were getting pretty beat up by the pair.
 
there is 3 behind the powerhead and 1 floating behind a peice of driftwood with tetra freely swimming by, I dont understand whats going on
 
how big is the tank? how is it decorated? exactly how many fish of each species is in the tank?

What are ammonia, nitrite and nitrate readings? pH? Temp?
 
55 gallon tank, big peice of driftwood in center of the tank that sort of divides it into two parts of the tank, and then clusters of short anubias plants on each side with a peice of slate rock on one side. 6 Serpae tetra, 7 Bloodfin, 6 Hatchetts, and 1 Pleco about 2 inches, and then the 4 angelfish.

Temp is 75, thats all I know about the water.

Another thing I will mention is that the angelfish look good in color, they are not faded at all.

ok I have an angelfish twirling around in the water now, it doesnt seem like it can swim, I dont know what the hell is going on its about to die
 
i just took him out and put him into a bucket with 50% new water... and then I did a 50% water change on my tank... I dont know if its the water, but I forgot to mention that earlier today I had a hatchett die also, so Im not too sure whats going on here
 
how often do you change water?

I would do a 50% water change at minimum--unless you do not regularly change water. Then I would do a series of smaller water changes a couple of times a day for several days until you could hit at least 50% without shocking the fish to death with freshwater (ever wonder why they are called "freshwater" fish?).

Get a test kit. It is essential to know (and understand) the ammonia, nitrite and nitrate levels. pH also is imortant in relationship to ammonia.

gh, kh, and temp can also provide helpful hints to determine possible solutions.
