My neighbors moved away and left behind a 37-gallon tank full of fish. They packed up, turned in their keys to my friend who is a property manager, and left the state. The tank was full of algae and the water level was low, but after some water changes, gravel vacuuming, and adding a UV
filter, the water looks clear now. I'm uncertain how long they were abandoned, but thankfully the previous owners at least left the heater on for them.
In any case, I have all these fish now. All of them seem healthy and get along, but there are definitely too many for the 37-gallon aquarium.
Here is the full stock:
Two large angelfish (3 inches top-to-bottom, 2 inches across)
Two plecos (about 3 inches each)
Two small silver sharks (about 2-3 inches each)
Three small red-tailed black sharks (about 1.5-2 inches each)
Three large tiger barbs (1 inch each)
Two dwarf gourami
1 mystery snail
I want to upgrade as soon as possible to a larger aquarium, and maybe separate some of these out. What size do you recommend? Would a 150 gallon be big enough or do I need something larger?
