The width will limit the tank size. The largest tank would be a 25 gallon tank. If you choose this size, make sure the stand can support upwards of 300lbs. That is what the tank will weigh once filled and set up.

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.

Thanks for reaching out about your fish fry and including photos of the tank. The tank size should be adequate but also depends on the number of fry being added. Proper filtration and oxygenation will be very important. Good luck.

Your tank may be overstocked which will contribute to excessive algae growth. Other causes include poor water quality, overfeeding, too much light and slow water current. Consider removing some fish to another tank or getting a larger tank. If you choose the latter, it will need to be properly cycled before you move fish. A general guideline is one inch of fish per gallon of water. Use the adult size of any fish you plan on keeping when estimating tank requirements. Put the lights on a timer. A photoperiod of 10-12 hours on and the remainder off should suffice. Increase filter flow if you can. Standing or slow moving water will promote algae growth. For now, you can use an algae scrubber to clean glass and tank furniture. Perform partial water changes and rinse filter media. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Use tank water, not tap water, to rinse filter media to preserve beneficial bacteria in the sponge.

Thanks for reaching out about your aquarium. Sorry not very good at botany but there should be tropical fish clubs that might help in identification. But comments about your tank. First, not sure if light penetration will be good for a plant that low in the water column. Secondly, the balanced rock formation looks tenuous, and might fall. Good luck.
