I have 3 tanks that all have two filters in them. They are (finally) all established. I was wondering how often I should clean the filter/change the carbon pad in the filter(s). I am terrified that cleaning the filter(s) would kill or eliminate too many good bacteria, so I'm at a loss here.

I have a 40 gallon tank with goldfish and minnows and a tetra whisper filter and some power filter

a 20 gallon tropical tank with two tetra whisper filters

and a 3.5 gallon tank with one betta and 3 mini tetra whisper filters

I'm so paranoid that I will kill bacteria by cleaning the filters that I haven't done anything with them.

Activated charcoal is usually effective for only a few weeks, because it gets clogged up.

To clean other filter elements without removing beneficial bacteria, gently swish them around in used aquarium water. Replace them one at a time and only when they are completely worn. Beneficial bacteria also live in the aquarium substrate, so a reasonable amount of cleaning will not substantially reduce their population.

Healthy bacterial colonies will grow in response to available nitrogen compounds.

Angelfish gender is obvious only when they are actually spawning. A few characteristics will help with the guessing, and here they are:

If you have two angelfish of the same gender, the contests will be primarily territorial. A courting pair will shake dance and posture and lip lock (remember those teenage years) then start jointly defending a territory. Two males will fight for dominance, and one will be vanquished. Two females have been known to deposit eggs together, but none of the eggs is fertile.

One way to get a spawning pair is to buy six juveniles from the same spawn. Since males tend to be larger than females, buy three large and three small angelfish. This is likely to produce at least one spawning pair, which will then need their own aquarium of adequate size.

It's one of many ways afflicted aquarists develop a case of persistent MTS (multiple tank syndrome). You are always welcome to join our informal MTS support group.
