After several months of just having just a yo-yo loach and an Oto (last suvivors) I ventured out on Monday and bought three long finned Serpae Tetras, 2 males, 1 female. Today I noticed the beginnings of Ich on the lip of the female. Question is Ick Guard II safe for these Tetras? I know I read something somewhere about Tetras having issues with some meds but I can't find it. This med is for scaleless fish and contains formalin (37% solution), victoria green, nitromersol and acriflavine. I have used this med before and still have some on hand. It calls for extra aeration but with the filter I have(Emperor the smaller one for 55gal tanks) I opted not to use more or the poor guys would be blown all around. Tank water moves enough to make the plants move very gently in half of the tank.
This tank is 20gal, fresh, set up 2 years, living plants,75 degrees F, water changed this morning (about 6-7 gal)-normally changed 2x week same amount, until new additions only fed algae wafers, bottom feeder wafers, shrimp pellets and on rare occasion frozen blood worms and this week added flakes back in for tetras, ammonia 0, nitrite 0, nitrates are up to 30ish.
With only the bottom feeders for a while is has been really hard to keep the nitrates down even with trying to remove the extra food (algae wafers) so these should start to go down hopefully.
Current occupants 1 Yo-Yo Loach, 1 Oto, 3 long-finned Serpae Tetras, 1 mystery snail, and a 2-3 Ghost Shimp left (loach snacks).
