I think a few members may have overlooked something with their stocking surgestions.
hi! i have a spare 5gallon (16*8*10) tank that is cycling now and i was wondering what would be good fish to put given that i'm in a tropical country and the water flow is a bit strong (200-300 l/h). it has an internal filter by haiyang (powerhead + sponge cartridge). oh and it's bare as of the moment, no substrate.
A 5gallon tank is rughly equil to 25litres
the filter flow rate is 200-300 litres per hour.
the tank turnover rate is beween 8 and 12 times an hour.
This means that there in a very strong current in the tank. IMO, the current is far too strong for Fighters, male guppies, cherry barbs or goramis, that origionate from areas with little water flow. Their large tails or bodies mean they have a lot of drag, and will realy have to work to swim against the current. They will not feel to comfortable in these conditions.
The tank is also too small for neons, that require a large amount of swimming space to feel comfortable.
I might surgest White Cloud Mountain River Minows. They naturaly origionate from the rivers source tributarites, thus realy like the strong current. They will also appreciate the high oxygenation leavles that the tank will have, if a venturi (airator) kit is fited to the filter. Place a few rocks at the botom for them to retreat to at night, and so they may rest occasionaly, and they will do well in the tanks conditions IMO.
