I am a lot like you in the fact that I need to upgrade my tanks very soon. However, you do have some very lovely fish. However, am not really a noob except with bichirs. Have had all sorts of fish over the years. Have gotta say I do have some compatibility concerns as well but also do acknowlege that if you are going off of information online, only get it here. I had seen bichirs for the fist time at a walmart and fell in love. I went home and researched it and thought I was prepared before I bought them. Turns out there is a lot of bad information online that just doesnt work. A lot of the articles and online info are just plain wrong. Now I go here and to a lady that works at Cayes because, thus far, these are the only sources that have not steered me wrong. Blue ram cichlids do not grow large enough to be compatible, jack dempsies are just plain mean and do not seem to get that the bichirs will eventually get mad at the constant pestering.......My bichirs killed one.......At first things seemed ok, but it did not last long. Most barb fish should be avoided. I have a large tinfoil barb now that does really well with the bichirs. The first ones I bought did not fare well and had to be taken back before they were killed. Nothing I have read mentioned pack mentality, but mine were hunting the barbs as a pack. I was pretty shocked, they were sorta corralling them and then striking......Never heard of such a thing in anything I read. Was not prepared for it. Now I have an african brownknife, the tinfoil barb, a rainbow cichlid, and two eels in the tank with the bichirs and it is actually more mellow than my community tank........
And as for the rude people posting here : We are all here out of a common love for our fish and our fish keeping. We all log into the forums for the common ground ( I am sure not everyone in our everyday lives understands our passions - at least, not in mine.) and for education that may not be as easy to obtain from other sources. Sometimes we all need the help of more experienced fish keepers. Everyone was a noob at one point and some people are more experienced than others. I bet you all made mistakes when starting out. There is absolutly no reason to be rude to someone new just because they are not doing things the way a more experienced fishkeeper would. Obviously they came here for help and not to be treated badly. So maybe some people need to check their arrogance at the door and try to help others instead.
