Molly Fish Is Pooping Clear And Resting At The Bottom Of The Tank

[Kitsune156]

Yesterday I got two male mollies for my new 10 gallon tank (my first fish tank

 ). One seemed very active and the other seemed kind of anti social(and smaller), so the more active one started picking on him. Because of this, I thought it would be best to get more fish so that the more active one would have others to play with. I decided to get a honey gourami, two more small mollies, and a snail, all of which are male. Once I came home he was in the bottom corner of the tank and I noticed that he was pooping clear with a little bit of white in it. After I put the new fish in, he started hiding behind one of the plants and the other molly stopped picking on him. The other fish don't seem to mind him and leave him alone (Btw the other fish seem comfortable and happy)
 
A few days before I got the fish, I added the suggested amount of water dechlorinator and some quick start in and let it filter with the heater on. I have a thermometer and it says that the tank is at 78 degrees. I also tested the pH and it was at 7.4. I think the ammonia and nitrite levels are ok because I put the quick start in, though should I put more in because of how many fish I added??
 
I don't know whats wrong with him, though I have read other posts like this that suggest that the fish have parasites or constipation, though I think the color of his poop may be because he wasn't fed well at the pet store because he was in a pretty overcrowded tank.(Idk I'm just guessing

 )

Can I just ask how long the tank has been up and running? Did you cycle it before adding any fish?
 
Yes, you are right, the clear poop can be down to poor diet and constipation and also parasites.  You could try cooking up and de-shelling some frozen peas which can help with constipation.  If it's a parasite then you will need medication that can help clear internal parasites.
 
If the tank has only been running a few days your filter will not be cycled and it will struggle to deal with the ammonia the fish are producing. This can stress the fish and make them unwell.  If you've not cycled I would recommend frequent water changes to help lower the levels in the water.

I let it run for three days before adding the fish. I will try the frozen peas method and see if that works because I don't think its parasites. I'll also try changing the water today (maybe 20%?). He seems a little bit better and instead of staying at the bottom all of the time, he swims around a bit more, though he is still pooping clear, so I will try the pea method. Thank you!

I'm sorry to say that there's no way your filter will have cycled in that time and it will be unable to process the ammonia your fish will be producing.  Change 50% water every day if you have fish in there to bring the levels down.  Make sure to bring the water up to temperature if you can (don't use water that's too hot or too cold) and use an additive to help remove any chlorine as this will kill off the bacteria in the filter and slow the cycling process.
 
There is a guide on cycling here : http/www.fishforums.net/index.php?/topic/421488-cycling-your-new-fresh-water-tank-read-this-first/
