I'm re-starting my 200 gallon heavily planted tank - high light with moss, swordplants, anubias, hairgrass. I'm trying to make it more of an ecosystem than a "fish tank" - I'm growing all kinds of critters in it right now (cyclops, daphnia, MTS, worms in the substrate, etc.) Once I get it all stabilized I'm going to add just a couple of small cichlids, probably rams, & let them go to town & see where everything stabilizes.
Right now the tank is in the "extreme green water" stage. Which is OK, because I've got daphnia & cyclops in it.
Problem is I opened up the cover today and found a newly molted damselfly.
Not the kind of critter I wanted in the tank.
It obviously hitchhiked in on some plants I put in the tank, either as an egg or larvae (along with the cyclops and lots of other small crawlies I don't mind).
I don't know if I've got more. I have no fish, and so I suppose I can just wait until any larvae hatch and die in the canopy. But there's no way I could ever see them or catch them if they're in the larval stage, even if I didn't have green water. Too many plants & rocks.
Or should I just remove enough of my invertebrates to restock and just wipe out all (animal) life in the tank? If so, how?
