There truly are a lot of different catfish species that I and many others can help you fill a 75 with. Perhaps you wanted to go with a mainly bichir tank? Our local poly group can help you. Maybe you want it to be a planted tank? I know Hendre has a planted tank. Rainbow wolffish? J jaws7777 had one with his bichirs if I remembered correctly. It's too small for any real predatory fish such as peacock bass or stingrays so they're out of the question. A severum would be nice. ryansmith83 is very knowledgeable about severums. If you want to go with a light stocking then Stanzzzz7 is your man. SharptoothBass is very knowledgeable about gobies, mainly larger ones but I think he could find a good one for your 75. kno4te and tlindsey have general knowledge so they could likely point you in a few different directions. I'm leaving a few fish species out, I'm sure of it, but I can't seem to think of any more. Fat Homer and Angelphish (I think) could talk to you about nano gobies if you want to make the other
5 or 6?!?! That’s expensive and it’s gonna be hard because they eat wormsId go with 5 or 6 upper jaw bichirs and call it a day.
Red wolf could be fun as well

I see that I've finally earned the reputation of the goby guy...yeah, im also into nano gobies but probably not quite as familiar as Angelphish on the subject...
However, with nano gobies, to be successful with them you need a very mature tank and even then they can be quite finicky to keep.
Add to that the often hefty price tag they can carry means they arent necessarily the best choice depending on experience level...
Will the stiphodon’s graze on nori/seaweed?I see that I've finally earned the reputation of the goby guy...
As stated they need a mature tank, but in my opinion it's worth the wait. The best way to describe them is a personable polypterus or eel. They greet you like a puffer or cichlid would, but also somewhat resemble eels since they lay on the bottom of the tank, and sometimes drag themselves across the bottom with their fins. Dependency on algae and biofilm for feeding various by species. Genus such as Stiphodon and Sicyopterus are more algae grazers, whereas sicyopus and rhinogobius are more carnivorous scavengers, so what you choose really depends on what you prefer to feed and the behaviors you find most interesting. Rhinogobius and sicyopus can be fed frozen foods such as bloodworms, whereas stiphodon tend to stick to various surfaces to graze algae.
I would assume so, as mine took algae wafers.Will the stiphodon’s graze on nori/seaweed?
Thanks man! Wow you’ve had fish before I was born? I thought about rainbow fish there pretty cool, I LOVE golden rams and gouramis would like 5 tangerine gouramis and 2 or 3 rams work in a 75 gallon tank?I’m actually trying to stock a 75g also. It’s not set up yet but I would like to plan ahead. So I don’t end up with a tank full of fish I feel nothing for, which is good advice.
I’ve been keeping fish for about 20 years now and I got a lot of enjoyment out of cichlids, over time I enjoyed he smaller ones more than the larger ones. I found that you get the similar behaviour at a much more manageable size. I found having a whole tank dedicated to one huge aggressive fish was more visually boring to me.
If you like cichlids there are so many options that would work in a 75g. Personally I like nicaraguensis and fire mouths. Medium sized, can live with other tank mates, well coloured and interesting.
Mbuna would also work well if you want to breed colourful fish.
Also consider rainbow fish, or a Biotopes aquarium like West African, southeast Asian etc
Good luck!
