a couple people have told me more than 1 chromis will eventually become 1 after time in a smaller ish tank such as 40g
according to live aquaria a midas blenny will nip at fire fish
im putting together a 40g nuvo tank later this week and when it comes time to stock im getting 2 clowns first, then a couple weeks later i will be adding a Banghai Cardinal, couple weeks after that ill add a purple firefish then 2-3 weeks later ill add a tail spot blenny after that im not sure what kind of fish i will add but definitely will add a few snails, hermits, crabsand shrimp in between the fish....after the blenny ill have 5 fish in the tank, i will most likely just let the tank run its course over the next few months and see how things work out. Im really leaning towards a wrasse, i really like the 6 lines but have read numerous stories on how they are jerks and a pita to catch if you want to remove them so ill probably just end up getting a possum wrasse....i really really want a mandarin but not sure if ill have a strong enough pod population to support a mandarin, well see what happens later down the road.....oh i started a thread similar to this not long ago, might be worth checking it out
