ok i went and got a stock that isn't permanent but for the most part if i've read properly would be ok for a little while. i had 1 lemon oscar and 1 jd and a minnow or mystery fish, i got a beautiful red oscar, 2 fire mouths (rare find in wyoming), 2 clown loaches, and a clown knife. they are all under 4" and i want some care info on which ever you know most about, i need multiple opinions, i will post pics when it settles as i re-arranged my tank to accommodate many hiding places for my fish. my jd is being a little aggressive toward my knife, but i think its just the new fish, i have a tank i could put him in if i need to. im more concerned about my knife because i have never had a knife before. what can i feed him? i have fake plants kind of sheltering half the tank with rock caves mixed in and then the other half is just rock caves. i am feeding the other fish blood worms and flakes. is this good for all of them? i am breeding mollies as the feeders for my oscars and wondering if this will work for the knife to. any ideas on what i can do is highly appreciated.
