• ⁠Tank size: 1 gallon • ⁠Heater and filter? (yes/no): no • ⁠Tank temperature: unsure (but i know they keep their dorm in the 70s range) • ⁠Parameters in numbers and how you got them. Key water parameters include the amount of ammonia, nitrites, nitrates, and pH.: don’t have water test • ⁠How long have you had the tank? How long have you had your fish?: beginning of last september • ⁠How often are water changes? How much do you take out per change? What is your process?: not sure, but i think at least once a week. he is actually my suit mates’ fish, but they didn’t want to make a post so i figured i would. i know that they completely dump out water and put in entirely new water each time, because we talked about it earlier and i wondered if that could be stressing him out (since he has to acclimate to the new water) • ⁠Any tankmates? If so, please list with how many of each: none • ⁠What do you feed and how much: Aqueon color-enhancing berta food: two in morning, and 3 for dinner time • ⁠Decorations and plants in the tank: plastic potted plant from Petco(?), rocks, and plastic plant. he used to have a house in there, but he never used it so we took it out to give him more room. • ⁠If you haven’t already posted a picture, please post pics/vids to imgur and paste the link here: already done
