Hi all, fairly new here, have had a huge love of aquariums and fish for quite some time, and I am finally getting to set up 2 46 gallon bowfront aquariums. while these are obviously too small to house any monsters in them, I was hoping to turn one into a Malawi tank, starting with maybe 10 babies, all 1 inch or less. The other tank is where I want the excitement of live feeding. I would like to have a clown knife (if purchased it will be about 3 inches), and since they tend to hide on the tank floor, I was going to put one or two needlefish into the tank as well. Both species will eat live feeders, the clown will get bloodworms/brine shrimp as well. My question is do you think that this is a bad idea since the clown will eventually outgrow the needles by a lot (40" to 12") or should they get along for the most part since one is always going to be on top and the other is on the bottom 99% of the time?
