Who's Killing My Swords?

[laknarf]

One of my tanks, a 55 gallon has 2 medium size3d Angels, 6 smaller sizede angels, 2 clown loaches,2 syno catfish and 2 smaller sized black sharks with red fins, NOT the aggressive ones.

I wanted to add some live bearers in order to supply the angels with live food and decided on brick red swordtails. I purchased a trio and at the end of the first day a male and a female perished. I went out a few days later and bought a pair and once again the new pair were gone by the following day. A few days later I tried again and bought another pair and once again by the next day they too were missing. The only sword tail that is still in the tank from the 7 that I bought is one of the females from the original trio. I know that swordtails have a tendency to jump out of the tank, however these "missing" swords did not jump out.

Does anyone have any idea as to who is killing the swords ???
I haven't lost any other fish in the tank
The water poarameters are perfect in the tank
Why would one of the original trio still be alive and all the others gone?

Thanks for your input

hmmmm my bets on whatever synos you have....just a suggestion though! someone else may have a better idea...

what synos are they?

Which type of black sharks are they? are they the red tailed black shark?

On another note, the tank isnt big enough for the clown loaches in the long run

What are the tanks water stats?

This could be a case of the water quality not being great. The original occupants sometimes adapt to cope with water conditions as they change slowly over time. However any new fish you add would simply perish and THEN be eaten.

This might not be the case of course. Just an idea.

How long has the tank been set-up and how long have you owned each fish?

What is cycled prior to adding fish?

Thanks for the replies...............

Curiosity101.....The water stats are good. The tank has been set up for 3 years. I had it as an African and about 2-[3 monthsd ago changed it over to a South American (Angel) tank

arobinson1984..........The black sharks are the ones with ALL of the fins in red and a black body. They are not the more aggressive red tail shark. As to the size of the Clown loaches. By the time they reach their maximum size I'll be long gone

MewMew42.....The synos are either the multi or the eujper*****. They don't bother anybody in the tank

What are the actual water stats though.

Not just Ammonia, Nitrite and Nitrates. Also pH, gH, kH.
Also it might be good to see a full set of stats for the tapwater. (obviously allowing the water to settle for a couple of hours prior to testing)

Im presuming you mean a black rainbow shark then?

2 smaller sized black sharks with red fins, NOT the aggressive ones.

Do you mean Rainbow Shark?

Although they are less aggressive than the Redtail shark thay are still aggressive fish!

 

[arobinson1984]

I have an albino rainbow shark and he chases some of my other fish from time to time, I've never seen him attack any of them and none of the other fish show any signs of being attacked but its something you may have to keep an eye out for in your tank.
