My wife and I are pretty new to caring for fish. We had quite a bit of learning experiences with things the last month or so but I felt like I finally got things down.. The current setup we have has not changed for about a full month. Prior to that we had a couple issues with amonia but since then I got a test kit and been keeping an eye on the levels and it looks fine.
Nothing has died in the tank for a while until yesterday. We used to have 3 dwarf catfish, 3 platys, 3 mollys, and 2 fiddler crabs. One of the two crabs was added 4 or 5 days ago but he actually died yesterday. Today we noticed one of the catfish is not doing so well and one of the mollys are not doing so well.
The catfish seems to have some discoloration inside, almost like spots, not white like the pictures I have seen of ick. He is floating on top most of the time but swims down to the gravel and eventually ends back up on top.
One of the mollys have some sort of discoloration on the top of his head. Seems like a growth or a bruise or something. I do know of the three mollys, there are an orange male (the one i am discussing), a pregnant orange female, and a marbled female. I should also mention he has been hanging out on the bottom and seems a bit more sluggish.
I have a couple of things I have been feeding them. We had a couple of african dwarf frogs about a month and a half ago that didnt make it due to the amonia levels.. so the crabs seem to like the frog and tadpole pellets and a lot of the other fish end up eating them too.. I also have frozen blood worms I have been giving them every couple days or so from the frogs, just to get rid of them.. they seem to like it as a nice treat.. then the regular fish food..
Lastly.. there seems to be some wierd things floating in the water now.. almost look like eggs or something.. not sure if its the pellets that wernt eaten that puffed up or what.. Please see the picures below..
Any help would be appreciated!
