i had a betta sorority in a 10 gallon filtered and heated tank..1 of them had to what i believe was ICH,white spots on her..i took her out and put her in something separate to treat her.i put her back in several days later.he eventually got ate at and died..about a week or 2 later.more of my girls started getting sick..they started to loose their color.gills seem reddish in color.
they were gasping for air,stayed at the bottom or rested in the plants i have.they slowly started to die off.all my girls died.ammonia was high,around 2ppm..nitrate and nitrites were at 0.ph was at 7.6..
not realizing exactly how long it can take to cycle.i did it for about a week then slowly started adding my girls,who all got along perfectly.i assume they had ammonia burns due to their symptoms.but i think it might have been a little more than that..
what does everyone think.should i leave the water and everything in it and use the tank as is.by the way its now been up and running for about 2 months.i did water changes about once a week.about a 25% change and about a 50% change once a month..
or should i completely disassemble the tank.clean everything.and start all over?im kinda hesitant because of the beneficial bacteria thats in there.but surly dont want to take the risk of any new fish getting sick.i checked the ammonia the other day after the fish had been out.it was about 1ppm.i can check again now if needed.i use API freshwater master test kit.
i thought about buying some rosy red minnows(fathead minnows) to use as a tester/help the tank cycle.but i want to keep them as a pet..and add maybe another betta in it with them or a schooling tank.
there are pictures of my tank if you click on tanks in aquariums above my avatar picture..
any ideas on what i should do?im not in any rush.my current betta is in a 2 gallon and is perfectly healthy.no other fish yet.
