Gautam Singh is the editor of Aquarium Life Hub and writes its longest reference guides, including the beginner setup walkthrough and the fish health hub. His own articles concentrate on freshwater species, feeding, and the diagnostic questions new keepers ask when a tank starts going wrong.
White haze, green water and a brown tint each point to a different cause. Diagnose cloudy aquarium water by colour and timing, then fix it without setting the tank back.
Mollies, platies and swordtails share one water profile and one habit: they breed. Here is the hardness, tank size, sex ratio and fry planning that keeps them healthy.
Compatibility is about size, temperament, water needs and territory, not just whether two fish look peaceful. Here is how to build a community that stays peaceful.
Angelfish tank size, water parameters, safe tankmates and how to handle the territorial aggression that arrives as they mature.
Reef lighting is measured in PAR, not watts or lumens. Here is what corals actually need, how to place them by light demand, and how to set a photoperiod that works.
How to culture live food for fish: brine shrimp, daphnia and microworms at home. Setup, harvesting, and how much it actually saves you.
A complete hub for aquarium equipment and upkeep: what each piece of gear does, how to size it, what to skip, and the maintenance rhythm that keeps a tank stable.
A complete hub for feeding aquarium fish: how much, how often, which foods suit which species, and why overfeeding causes more problems than any disease.
What aquarium plants actually need, the difference between macro and micro nutrients, when root tabs beat liquid dosing, and how to choose a fertilising routine.
A step-by-step diagnostic for unexplained fish deaths, working through water quality, equipment and disease in the order that finds causes fastest.
