just ordered a new 10g tank & i have no clue what to put in it. im planning on a coldwater tank bc i dont want to have to order another heater (my house can go down to the mid 60s in winter so good heaters for tanks can be expensive). any ideas of what to stock? im not planning on having many plants as the led lights that i have are very low and im trying to save money on this by not getting all new stuff the tank comes with a basic hob although some have described the flow as a bit much. please give suggestions!!
