I am concerned about an over population of marigold sword tails in my 75g heavily planted tank. It's not an issue yet, but I'd like to do something now before the other fish are lost in a sea of orange and yellow. Could I find a fish that might be aggressive enough to cut down on the fry and sniff them out of all the leafy hiding places?
My current stock contains 2 SAE
's, 2 zebra loaches, 1 emerald cory, 1 black molly, maybe six neons (the neons are getting old and have been dropping off every few months), around 10-12 swordtails,and about 8 silver fin/similar tetras. The community is such that there is no fighting or aggression at all. I keep the tank very clean and the nitrates at around 10 at any given time. It's run with pressurized CO2
if that matters.
I'd like to find a more natural solution than bagging swordtails and dumping them in a LFS
. Any ideas? I thought tiger barbs could be an option after my neons all finally pass on, provided I get some that are young enough.
Thanks for the advice!
