Hello. I'm new to the forum, but I've been reading on here for quite a while now. I love reading on here, and decided it is time for me to join. I have some questions, I hope I have this in the right section. I purchased a 55 gallon aquarium off Craigslist, and these are the fish it came with: adult rainbow shark.. around 5" (not sure of age) adult clown loach.. around 7" (8 years old) adult Chinese algae eater.. around 7" (9 years old) 2 black neon tetras 1 neon tetra 2 red eyed tetras They all appear to be very healthy. They had the 3 larger fish since they were babies. I was told all the fish get along, and so far I haven't seen any problems. The 3 larger fish like to be by eachother, and even cuddle up together in a big log. I haven't see them going after the smaller fish so far. My plan was to move my 6 tetra glofish, and albino bristlenose pleco from their 29 gallon tank to the 55 gallon tank with them. I am wondering if this will be okay? Is it okay to have the tetras, and bristlenose pleco in with those larger fish? Is the tank big enough? When I was getting the tank they said I would have no problems adding my fish, but after doing some reading and thinking, I am wondering if it's really true or not. I really need some advice on this. I haven't added my fish yet. I have no idea if these fish are all compatible, and if the tank is big enough. I don't want to lose any of my fish. I was able to get more accurate measurements on them today, so I just added their correct size. Thanks for any help you can give.
