Hi all.
I recently bought a 70 litre tank and some fish:
6 neons
6 rummy noses
1 angel
2 mollys
I also bought some supplement that allowed me to fill the tank and add fish the same day without waiting for the filters to bed in.
All seemed well for a week or two and then I bought a few more:
4 neons
4 rummys
2 gouramis
1 molly
Then I found some of the neons had died. One of the mollys bullied all the other fish a lot a caused one of the other mollys to get stressed and her back twisted. The bully was female, the other 2 were a male and a female.
The one of the gouramis died. Then the neons started to drop like flies, 1 a week.
A few weekends ago I got the water tested and it was found to have a ph of 7.8. A bit high. I added to bog wood and another plant. Left it for another week and got it tested again. Still high, 7.8.
After this i done a 60% water change as opposed to the 40% I had been doing every 2-3 weeks up until then.
I added 2 more fish, a molly and a small catfish.
Nothing seems to improved and I'm losing 1 fish a week. Today i found 1 gourami, 1 neon and rummy nose had died.
What are the possibilities?
1. High ph. I tested the tap water we added and its a perfect 7.0 so something in the tank is causing it go high. I'm not sure what else it could be now, the gravel?
2. Underfed/overfed? I feed them twice a day, enough for them to consume in 30 - 40 seconds. The gourami was very slow to feed and lost out to most of the faster fish. Maybe he starved?
Any suggestions?
EDIT: I forgot to add, I've changed the filters when needed too. White (top) filter, once every 1-2 weeks. Green filter every 4-6 weeks. (I think it was the green, might have been the blues). Haven't changed the black (bottom) filter yet.
See pic of tank contents. There is 1 fake rock, 1 fake plant, 2 real plants, bog wood and gravel.
