I was wondering if my tank is big enough for them to be happy. The tank is currently 90L. Thanks!
Thank you for using Boop by Petco! It looks like the tank provides enough room for Speedy and Explorer to swim comfortably. Keep an eye on them, and move them into a larger tank if they get significantly larger or you notice signs of fighting or increasing ammonia levels in the tank.

What type of saltwater fish can I have in a 10 gallon tank
Thanks for reaching out, the rule of thumb is 1" of fish per 3 gallons, but smaller tanks are very difficult to keep stable, and saltwater fish are easily stressed by environmental fluctuations (salinity, temperature, dissolved oxygen). Good luck.

Please help!! I have a 5 gallon fish tank starter kit. Water conditioner. Thermometer. And it has a filter. I have bought 3 gold fish all from Walmart. (I know bad idea) and all have died 1 first day. 2nd one the next day. And the third is dying curr
A 5 gallon tank is insufficient for goldfish. They produce a larger than normal bio-load (wastes) that can quickly overwhelm a small tank. Ideally, one goldfish should be in a 20 gallon tank with an extra 10 gallons added per additional goldfish. The filter should be rated for at least twice the volume of the tank. They are likely succumbing to ammonia and/or nitrite toxicity. If you test the water, it is likely both parameters will be dangerously high. Perform a 50% water change. Use only conditioned water that is temperature matched to prevent further stress or shock. Goldfish are cold water fish and do best between 65 F and 72 F. Plain aquarium salt, NOT table or Epsom salt, can be used to reduce stress, improve gill function and aid in recovery. Dissolve 1 teaspoon per gallon in a cup or two of tank water and gently pour it into the tank. Treat for no more than 14 days then perform a partial water change to decrease salinity. A 5 gallon tank would be appropriate for one male Betta

I want Angel Alvarado to answer this question. What fish can i put in a 3 gallon tank besides shrimp. If I have to get neon tetras please tell me how to change their water. Thanks
The small size will limit the species of fish as well as the number. White Cloud Minnows or Guppies would do fine in a small tank. You could keep no more than 2 or 3 fish total. If you are looking for company for your Betta, the same species can be kept. Other options include Otocinclus (Otos), Corys, Platys or Harlequin Rasboras. Again, no more than one or two in addition to the Betta. Water changes for any tank are simple. Change no more than 30% total volume at a time. Use a water conditioner to remove harmful chemicals and make sure the water is temperature matched to prevent stress or shock. Rinse the filter in tank water, not tap water, to preserve beneficial bacteria. Vacuum the substrate every couple of weeks.

Hello! I just got a betta fish yesterday, and i wanted to make sure he is happy in his tank. He is in a 2.5 gallon tank, with a filter, (no heater) with two snails (1 nerite snail and one assassin) how big should the tank be, and what do i need for h
A 2.5 gallon tank is fine for a Betta and 2 snails. If you have artificial plants, use ones made of silk instead of plastic which can harm delicate fins. You'll need a heater also. Bettas are tropical fish and do best between 78 F and 80 F.
