notronaldreagan Posted August 29 Share Posted August 29 I have a 75 gallon planted tank that currently just has 2 gold rams and 2 bolivan rams. Id like to add a large school of tetras and then eventually add discus once the tanks matrues. How many tetras could I add at one time without adding to many for a new tanks bactiera is like 25 to many. And how many could I have in a tank with discus. Im just not sure how to count smaller fish into the bioload of the tank Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted August 29 Share Posted August 29 Remember that bioload is really based on food. I added 20 cardinal tetras to my 55 gallon. I also did 24 black neons to my 29. Add them, slowly up the food over the coming weeks to give the bacteria time to catch up and you’ll be set. 1 Link to comment Share on other sites More sharing options...

Im just not sure how to count smaller fish into the bioload of the tank Depends on how long you have had your tank up and running. I have a very heavy planted aquarium that has been set up for over 4 years (I have a sponge filter and a Fluval 307 Canister). I wouldn't be afraid of adding 30-40 Cardinals to my tank in one shot. (The amount of beneficial bacteria and the amount of plants, it really would take a lot for me to get an ammonia spike. The floating plants along with all the other plants just remove the ammonia, nitrite and nitrate out of my tank. I have been testing my water and I barely ever have any nitrate in my water. Plants are your friend.) I believe I could get away with doing water changes once a year if I felt like it. 1 Link to comment Share on other sites More sharing options...
kevin222 Posted August 30 Share Posted August 30 For your 75-gallon planted tank with gold rams and Bolivian rams, start with 10-15 tetras and monitor the tank's bioload and water params. You can add more in a few weeks if all good. Link to comment Share on other sites More sharing options...
