hmm. Sorry, this might be hard to hear but ...


Not at all, I was prepared for the worst. I'm not an experience fish keeper ( hence the choice of Biorb ) and so any advice is taken gratefully.

First off you're overstocked and without results for ammonia, nitrite and nitrate you don't know what effect this is having on the water quality. You need to get a decent liquid test kit as soon as possible. The API mini-master freshwater test kit is my favourite.


Wow, I am certainly glad I didn't follow the manufacturers recommended maximum of 12 small fish. What is the most fish that can safely survive in the Biorb?
Right, I'll go out and get one of those kits straight away.
I guess I need the results before asking for advice on how to adjust.

Second problem is that its a biorb, really terrible gas exchange and filtration. I don't think anyone has had a fish live a full and healthy life in a biorb, especially a 30L.


Because of the small next of the orb? That's partly why I keep stocked with plants. Do they not help as much as I expected?

Water change of 50% is too much in one go and every 3 months is too long between changes. 20% weekly would be far better for them.


OK, I'll try to adjust my schedule. I think that will be possible, as changing 6 litres will be a lot faster and easier than 15.

When you say you put a new filter in do you mean that you completely replace the filter as per the biorb instructions? This is actually very bad for the fish as the tank will have to cycle all over again and never reach any sort of biological stability. (see signature link for explanation on the nitrogen cycle)


I'd read on here previously that changing the sponge was a bad idea, so I have been throwing away and replacing the charcoal/coral mix that's in the bottom and keeping the sponge.

What are you feeding them?


Flaked fish food made by Tetra.

From what you've said so far I believe this is not a parasite but instead you are seeing the long term effects of biorb housing, nutritional deficiency, water quality and stability issues and cramped conditions. There is little that can be done except to improve nutrition and get a proper tank.


OK, I'll get on with testing the water and adjusting as required. If you have to recommendation for food, I'd be glad to hear it. Thank you very much for the advice/help.

all that said, can I finish on a positive note. The normal life span for a WCMM in captivity is 3-5 years so you're not doing all that bad by average keeper standards.
In the wild they live to around 10 years though and this is the guide that I believe we should set our standards by.
I can highly recommend a rectangular tank of 50L upwards with a good quality filter and large airpump.


That's a relief, with my bad efforts, I'm doing average. If I can up the effort, and have some healthier fish I'll be very happy.
