All day my choice has been GSP but i'm not sure if i like the idea of having to convert to full marine eventually. Would i need a protien skimmer? Different heater and filter? Plus the extra cost of using more salt.
Then if i do go for F8s i might just stick with them as the gobies are difficult eaters, i don't want to be spending a couple of £ a week on fish food as they'll only eat live.
Will piffers eat Malyasian Trumpet Snails? I could buy 30 of them for a few £ and put them in a tank to multiply and give me a constant supply of food, plus a bag of live food a week which costs about 40pence.
Will they eat household pests like spiders and woodlice, flies?
I might just go for what will be the cheapest running costs? Got a baby coming so i don't want a tank costing me around £5 a week.
