The ones I like is the Simease fighting fish. They say you cannot keep males together. Can you keep females together? How do you sex them?
and I wouldn't buy one from one of those Cups chain stores sell them in. Get yours from a proper aquatics shop who know what they're doing.;D
But saving them from a plastic cup death is so rewarding! its great to see them start swimming around in a nice 10 GAL settup streaching their fins
I agree, it doesn't sound like toxins are the problem, so the next most-likely culprit is that bettas and guppies are not compatible, and most bettas are not good community fish. This set-up can cause stress for the fish.
Having 0 nitrates does not automatically mean that the tank is not cycled. Live plants process nitrates, so it is feasible to get these readings in a cycled tank. I see that you have a planted tank, so I think you are good to go.
I am using a tablets at the moment but I am going to get a apI liquid test kit next week I have run my tests again and I have got a reading on the nitrates of 10 mg/l I must have not left it long enough I use tetra aqua safe for the tap water and tetra easy balance and nutrafin cycle for biological supplement when doing water changes and the filter only gets cleaned when it needs sorting out and when cleaning I clean in a bucket of the same water from my main tank and the gravel gets cleaned when I do water changes
I don't recommend keeping any other fish with goldfish apart from other goldfish, dojo loaches and other pond fish.Should I bring the other one back and if so could I put a different fish with the one I'm keeping?
Yes, goldfish are social.Would he get lonely?
