brought a 300 litre aquarium 10 weeks ago, have added lots of plants, and added 6 neon tetras last week and 6 rummy nose the week before , just got 4 corydoras this week, I squeezed the old dirty sponges from my old tank which is about 5 years old now to start the cycle , tested the water everything spot on, going to add some discus in the next few weeks, a bit put of when I read a lot of people have had there neons or rummy nose attacked and eaten by the discus I always thought they were compatible with discus any one had this experience with discus, may be put larger fish in to prevent this , any comments or ideas would be appreciated
thanks
