What the heck is this? It seems pretty harmless now but it seems to be slowly growing in numbers. It first appeared a week ago just after I redid about half of my tank. I think this may only be the first wave. Water change tonight.
Thanks Steve. I'm going to do a water change tonight, and I guess every few days for a while. Will that starve the remaining hydra? I dread trying to gather up all the fish but the ammonium nitrate idea could be a future option. How will the plants handle it? So far most of the research that I have done concerns itself with tanks with fry and not planted tanks.
Any other ideas are appreciated.
Your info is so appreciated. These are strange creepy little creatures. The water change took some out but I still see a few. Will fluke tabs have any negative effect on the plants, fish, or shrimp? I think my LFS will get a visit tomorrow.
Here is some interesting reading that I found regarding my new little "monsters." It figures I have to get critters in my tank that are actually named after a Greek monster.
I wonder what they could be eating in my tank. I have no fry (maybe some shrimp eggs) and I feed the fish flake food only. Hmmm... Maybe they will starve. Maybe they have been dormant in my tank. I have done some big changes regarding KH, GH, and PH. All are higher because I am installing a new Co2 system and I am trying new methods to keep these water parameters. I guess I should start to cycle a quarantine tank for my fish and shrimp in case these things start to grow in numbers.
