Help ...how many fish is okay for a fluval evo

[Defff21]

I have a fluval evo with 2 clowns and an algae blennie...i want to add a royal gramma or will this be too much bio load ?

Fluval 5g or 13.5g? I have a 5g and only keep a yellow watchman goby and pistol shrimp and with weekly 20% water changes my nutrients stay pretty high. So personally thats enough bio load for my tank. Sounds like yours might be near maxed already, what are your parameters like?

I do about 30% weekly and my params are always OK, i thought it might be a bit too much alright..especially since I run no skimmer

Time for a bigger tank
