And nice to meet you since I am new to the forum! :) Would really appreciate some input from you for one of my neon tetras. It has developed a red growth on its mouth (see picture attached). It has actually grown more within the last week.
I bought Melafix for bacterial infections but haven't seen any improvement in the last 3 days.
Have you come across anything like this before and do you have any advice?
Hi I was wondering if I could get some advice I currently 5 fancy goldfish in a 200liter tank i do a 25/30% water change a week and also have plants in the tank as well, should I upgrade the tank or is this okay?
Nitrate is the final product of the cycle and is not processed by the filter, so no matter what size filter you have, nitrate will always rise relative to the number of fish, amount fed, etc. It can only be controlled by watr=er changes, but as a lot of the UK has nitrate in the water supply, it will never be lower than the amount you have from the tap. I would do another water change of about 50% to get it down and then increase your regular changes to 25% per week.
New here, reasonably new at fishkeeping - learning every day!
I have a 60l tank which I moved just 3 danios into a few months a go - the aim was to get more but lock down happened. They used to be in a much smaller tank so became quite stressed with just the three in such a big space. They developed what appeared to be gill flukes and possibly tape worm (no obvious worms but they were still eating a lot and were quite swollen). Treated this with fluke solve and filled the with artificial plants so they had plenty of places to hide. All seemed fine, tank was nicely cycled by the time lock down eased. I’ve introduced 6 new danios so they have a nice sized shoal, everyone seems very happy and active. I expected a spike in some parameters, had a tiny bit of ammonia which seemed to correct quickly with water changes. Nitrates were below 5.0ppm.
A few weeks on and I’m getting the odd hint of ammonia every now and then (below 0.25ppm but definitely a slight tingle of green using API testing kit), the nitrates have shot up, 80ppm a few day’s ago, water changed then but still at 40ppm when testing today. Nitrites are consistently 0. I did have a major algae outbreak when the newbies were first introduced but cleaned this and now the regrowth is minimal. I do 10% weekly water changes, should I up this?
They’re only fed a pinch of flakes once a day or half a block of frozen blood worms twice a week.
I know they’re producing a lot more waste compared to just 3 but my filter is for a 200l tank so really should be able to handle 9 little danios. One injured her mouth and developed a little growth so I had to remove the carbon to treat with Esha 2000. Do you think this is why? They all pooped a lot during the treatment too (brown but a bit stringy).
Any tips on keeping the nitrates down? I’m a little nervous about adding live plants as I’ve seen that they can potentially make the problem worse - am I worrying for nothing?
I love these little guys and want to get on top of this while they’re still happy and healthy.
