Hi all and thanks in advance for any advice or comments. I'm new to tropicals but have done some research to try and avoid any really stupid errors ! I have a 64l tank which I cycled with tap safe and filter start. Test readings were all good so I began stocking. A few fish each week along with more tests and small water changes. first off 6 small guppies 'bumble bees', a week later 6 neon tetras and finally 6 'sunset' platys. At this point all is well test readings good and all appearantly getting along.
I share all of the above just to set the scene a little. So then I notice one of the platies seems to have a problem with his dorsal fin and a fin on one side, I can't be certain he didn't arrive like that but I'm pretty sure. After several days of paying lots of attention to the tank I found the cause last night, a neon ! I was under the impression they were nice friendly fish ? So I've removed the injured platy into a quarantine tank and kept a close eye on the neons. They appear to be being very aggressive towards eachother. So is this natural neon behaviour or have I done something to cause it ? Am I misunderstanding the neones ? What can I do about them ? Will the poor platy recover ? Thanks for reading all advice, comment gratefully received.
Thanks
Chris
