HELP PLEASE !!!! ! Just joined this group hope anyone could help . I have a 5 gallon tank (cycled) which i am housing male crown tail betta . My son woke up from his nap earlier then expected and put about 5 prenatal vitamins in the tank when I noticed they have already been dissolved. The tank was completely yellow I transferred betta into a temporary bowl to clean out tank. I thought i could just do a 90 percent Water change but this stuff was everywhere I had to rinse put everything! He's back in the tank. Is there anything else I can do ??? Thank you any input would be great!
