I got a 240 liter tank with 5 medium sized discus and assorted tetras, i have had it for about 8 months or so and all has been good, recently my fish got gill fluke so i had to treat with parasite tabelets, at this time i also had to go interstate for work so i had a friend come around and take care of the fish, while i was gone i think they did the treatment for 3 weeks rather then 1 and in turn all my plants died, now that im back the fish look fine but i had to removed all the dead plants and fix up the tank. i got all new plants for the tank and now the discus are very scared of me all the time, if i get up off the couch or go anywhere near the tank the discus all freak out and dart across the tank. they use to be very friendly and come and say hello at the glass. I'm guessing this is because of the new environment layout, although its been over a week now and the discus are still as scared as ever, any suggestions?all water chems are good and they are eating as long as they cant see me.
