I am not sure what to do. I introduced two corys to my 10 gallon tank a few days ago and they seem to be doing fine except that I have one Platy who follows them around and then pushes or nips them out of the way when they are digging in the rocks to eat whatever they were digging at. I made a mistake the first time I fed them and gave it to them during the day and the platy ate nearly all of the pellet and her stomach blew up like a balloon. She is fine now but she is pretty consistently harassing them. I also have a Zebra Danio that will take time off of the other 2 zebras to chase one of the corys around. I am concerned. Is thee anything I can do or do I need to just wait this out? I am picking up a 33g long tank this weekend and will get it up and running which will be the corys, zebras and platies new home but in the meantime I am worried they will get nothing to eat and if I try to feed them extra and some food falls to the bottom, my platy tends to get to it first. So it seems that the corys aren't eating and the platy is getting too much. I also didn't realize when I put the corys in that my gravel is a little too large for them so finding food is tricky because it falls in the cracks where they can't get it. I did put some handfulls of smaller gravel in there that I will try to stick a pellet in tonight after it has been dark for a while but I am still worried that the darn platy will still sniff this out. Is there anything I can do and will this behavior subside once they are in a bigger tank. I currently do 30% pwc once a week and monitor my ammonia and nitrites/nitrates pretty closely. There are only the 2 cories, 3 zebras and 2 platies in the tank now. One platy is older (over a year) and is now kind of getting skinnier and skinnier so I don't believe he will last much longer. I know platies school more loosely but when they are in the bigger tank and I can add some more platy friends will this help? I know this was lengthy but any advice would be greatly appreciated.
