African Dwarf Frogs not eating
I've had a pair of male African dwarf frogs (Sam and Pippin) living in a two-gallon tank for over a year and I've never had any trouble with them until now. Last week I changed their water and in the process I replaced their old gravel with new, added a plastic plant, and a plastic tank decoration.
The first couple days after the water change, the frogs were extra frisky like they usually are when they get new water. But since then they, especially Sam, have been fairly sluggish. They spend most of the day near the top of the tank sitting in the plant's leaves (again, Sam does this more than the other). I thought "Maybe they just really like the plant.." but it seems they haven't been eating much/at all either. I put in the normal amount of pellets (I know not all frogs like pellets, but I've been feeding them pellets for over a year and they've been fine up till now) and the pellets just sit at the bottom, getting soggy and clouding up the water.
Tonight I took the plant out and Pippin has been swimming around and being pretty active since then, though I haven't seen him eat yet. Sam has been sitting in mostly the same place.
I'm really, really worried about them. What could be wrong? What caused it? And most importantly, HOW CAN I HELP THEM?
