im reasonably new to keeping tropical fish, my tank had a 2 week fishless cycle and after that i first added a male betta, 3 cherry barb and 3 gold barb i have now acquired 3 bristlenose catfish ( they where free from my father in-law as hes wont stop mating) and had to buy 5 assassin snails as i was having a little problem with some ramshorn id had hitch hike in on my plants. i was just wondering what would be a good addition as im looking for something maybe a bit colourful and active.
