Dog-eating Tetra

filtration? all i know is its an aquaone tanks that has a filter built into the hood and i do water change every fortnight.

i have abandoned the barbs and now ooking at some guppies and gouramis. i have just got 3 neons and 3 glowlight tetras.

i have a 75ltr tank and allready have 3 neon tetras 3 glowlight tetras and 2 bristlenose and i was wondering if anyone could tell me about how many more fish i could have? i was looking at 2 pearl gouramis, 2 dwarf gouramis, 2 chocolate gouramis and 5 guppies. would this be too much and do i really need the bristlenose's in?

im not really sure what cycleing is but i put thoses bristlenose's in because the guy at orgamism said they would be good.

i have 2 bristlenose i think and i was told to feed them 1/4 of a jbl pleco tablet every night but i am finding some seemingly untouch 1/4 tablets on the gravel and wondering whether i am feeding too much or they just aren't finding the food. should i only feed every second night or is it nothing to worry about?

its a 75ltr tank and ive had it setup since about the 16th of october so coming up to a month now and would barbs intergrate with each other?

im thinking of getting some barbs like some golden, cherry and odessa barbs and wondeiring if they would be ok if i had 6 odessa barbs and 3 golden barbs and 3 cherry barbs because i don't want 6 of each but i thought they needed to be in a school.please can someone give me some advice? also im getting some new fish as i only have two bristlenose i think they are and im new to this.thanks
