New guys not doing so well

:'( I have recently added two new male swordtail to my tank. Previously there were only 3 tetras and 4 zebras in there. (30 gallon tank)The new guys are not doing well. I never see them eat they hide behind the same plant all day long and their color is fading. They just lay at the bottom all the time. Any advice on how I can help them adjust better. I have added stress coat and some of that "bacteria in a bottle" stuff but there is no change. Poor little things I hope I can help them some how!

 

What are the ammonia, nitrite and nitrate readings of you tank? How did you acclimate the new fish prior to putting them in the tank? More info is need for us to help you figure out what's up. Welcome to Fishlore!

 

Everything is ok. No problems with the water. Are they just passive fish? ???

 

No They are not especially passive fish. They sound like they are showing signs of stress or discomfort.
In order to help you we need certain information. We need to know how long your tank has been set up. Also ammonia, Nitrite and Nitrate readings.
If you don't have a water testing kit some fish stores will test your water for you. ask for the numbers not just is the water ok. Would be very beneficial for you to be able to test your own water.

One of the new fish has an ulcer. I have been looking online but can't find a treatment. Any advice?

 

We still need the answers asked in the previous post then maybe we can help you. thanks

Here's a couple of links with more information:





What I've been told to do in the past is to quarantine the fish and start treating with Maracyn I and II according to the directions.

Also, please answer the questions already asked. Thanks!
