Guides & advice
Aquarium Guides
Fish That Live with Shrimp
Which fish can share a tank with shrimp, how plants and hardscape help shrimp survive, feeding both, and whether shrimp can still breed.
Shrimp Safe Fish List
There is no fish that can be guaranteed completely safe with newborn freshwater shrimp. If a shrimplet fits into a fish's mouth and the fish recognizes it as food, predation is possible.
Snail Compatibility Chart
Freshwater snails can live peacefully with many aquarium animals, but compatibility depends on more than whether a tank mate is labeled peaceful.
Betta Tank Mates
Can bettas live with tank mates? Tank size and territory, suitable fish, shrimp and snails, fish to avoid, introducing them, and a backup plan.
Goldfish Compatibility
Goldfish compatibility: fancy versus single-tail goldfish, other fish, snails and shrimp, temperature and feeding, and space and filtration.
Corydoras Tank Mates
Good tank mates for corydoras, from peaceful midwater fish to shrimp and snails, which fish to avoid, and how to introduce them safely.
Amano vs Cherry Shrimp
Amano shrimp and cherry shrimp are both popular freshwater aquarium invertebrates, but they suit different goals.
Peaceful Freshwater Fish
A peaceful freshwater community is built by matching behavior, adult size, social needs, water chemistry, and swimming space—not by choosing fish that happen to be sold under a “community” label.
Fish to Avoid with Shrimp
Which fish eat or harass shrimp, including cichlids, puffers, loaches and some bettas and gouramis, and safer choices for a shrimp tank.
Weekly Aquarium Maintenance
Weekly aquarium maintenance works best when it is boring. You should not need to rebuild the tank, replace half the equipment, or scrub every surface until it looks new.
Monthly Maintenance Checklist
A monthly aquarium checklist: inspect equipment, service the filter without losing the biofilter, clean, trim, and review water and livestock.
