[fishy freak]

Hi fellow fish lovers, I just discovered this site, it's good to meet you all, here's my problem:

The water parameters are all good PH 8.0, Nitrites 0, Nitrates 40, Ammonia 0, (GH & KH have always been on the high end), fish are active, young, eating very well, but they keep dying on me for example, I have a shell dweller, king of his domain, next day he was hovering at the bottom and wouldn't eat. Next day (yesterday) he was pale and very weak, I'm guessing he'll be dead when I get home tonight, that is if he didn't die overnight. These mysterious deaths have been going on now for a few weeks and I've lost about 5 fish, hopefully whatever it is passes and maybe it's just a fluke. I set up a 180g tank and stocked it with about 40 various African Cichlids, introducing Ich (they didn't charge extra for that). Ich was treated with Cupramine, took about 4 weeks :/ over the last 2 water changes (25% weekly) I stopped adding the medication, they seem to be doing fine.

I know there's still a lot of unanswered questions here and I'll be happy to answer any of them. Any idea's?

Welcome to CF!

What is your stock list on this tank?

IMO, those nitrates are a little on the high side for comfort. It's always better if you can keep them around 20 or below, so you may need to increase the frequency and amount of your water changes.

How many gph are you putting through your filtration?

What is your tank maintenance routine?

How long has this tank been set up?

How did you cycle it? Did you use any of the fish you are losing to cycle the tank?

What other species have you lost? Any symptoms before death?
