Aclimation
Prepare the Tank:
Make sure the new tank is set up with proper filtration and has been cycled to establish beneficial bacteria.
Check that the water temperature, pH, and other water parameters match those of the water the guppies are coming from.
Float the Bag:
Place the sealed bag containing the guppies in the new tank. Let it float for about 15-20 minutes to equalize the temperature between the bag water and the tank water.
Add Tank Water to the Bag:
Open the bag and roll down the top edges to create an air pocket so it can float. Every 5 minutes, add a small amount of tank water to the bag (about 1/4 cup). Do this for about 30 minutes. This helps the guppies gradually get used to the water chemistry in the new tank.
Release the Fish:
After the acclimation period, gently net the guppies out of the bag and place them into the tank. Avoid pouring the bag water into the tank to minimize the risk of introducing any potential contaminants.

Square Sponge Filter (Loaded, For up to 40 gallons)
Square Sponge Filter (Loaded) – Dual-Layer Sponge Media, Quiet Filtration (Up to 40 Gallon Aquariums)
This square sponge filter (loaded) is designed for aquariums up to 40 gallons, offering strong yet gentle filtration in a compact, easy-to-place design. The square shape provides more surface area than round filters, improving both mechanical and biological filtration.
Pre-loaded with dual-layer sponge media, the outer sponge captures debris while the inner layer supports beneficial bacteria that help keep water parameters stable. Powered by an air pump (not included), this filter runs quietly and creates smooth water movement that won’t stress fish.
Because it comes fully loaded, it’s ready to use right out of the box—just connect an airline and drop it into your tank. In my opinion, square sponge filters are a great middle ground: more filtration than small round sponges, but still simple and fry-safe.
