And I know the bumblebees are brackish but I have also read that there are freshwater ones too. Either way they have been in there since may. Also my feeding is about every 3 days and I feed either frozen brine shrimp, frozen bloodworms or frozen emerald which is a veggie one.
Sorry if I missed this, did you test nitrates in your tap? You might consider larger water changes (50%).
How much do you feed them?
Maybe feed them smaller amounts every day, i would think the bioload produced in smaller quantities / gradually, could possibly give the fish a better chance to adjust to the nitrates...'m not an expert but people always talk about taking into consideration everything you put in a tank, including food
Yes I did, and the nitrates where at a 5! So I might start doing larger water changes. The ph was at an 8.8 and ammonia and nitrites where both 0.
I just retested my tap water and it's 10. It's difficult to tell between 10 and 20 on the API nitrates test as the shade of orange is similar.
I'm usually happy if I can keep my nitrates in the orange. I can do that with a 50% WC per week (and feeding once p/day). Sometimes I do two 30's instead of one 50%. You should be able to get a feel for what it takes to keep your nitrates under 40 ppm. If the test is red, do a water change.
Good Luck!
