The Red-tailed Shark Minnows (RTSM) are eating at algae on aquarium much of the time but I cannot see changes in coverage even though the fish are clearly ingesting it. I started cleaning the front glass only and all fish quickly increased gut fill. Largest fish appears to be female based on...

Thanks for access to the PDF. Information provided on behavior. Sampling method was not indicated. In my experience habits like that yielding the single fish are difficult to get representative samples from by seine or electrofishing, especially with benthic oriented species that like to retreat...

Behavior in ponds. Culture ponds if need be.

I do not think the solitary assertion is correct. That description does not appear based on extensive study of the fish in the wild. Level of info is what expect would be provided by someone doing filed collections without actually watching the fish.

The water flea going in my tank currently has not been looked at closely enough for ID. Today I will make a few pulls with plankton tow net to up culture a bit. My culture feeds on a phytoplankton bloom driven by sunlight and chicken manure.

What I would really like to see are videos and detailed written accounts of the Red-tailed Shark in its natural habitat. I am coming to the thought they are in relatively high density groupings with lots of social interaction over well defined territories and home ranges. The tank to be run...

I wish someone with experience keeping them and trying to breed them would make them-self available.

I did not make video. It does give insight to take advantage of. My fish are getting along better. Will be watching gut fill. If someone gets lean, then they will be pulled. Greater gut fill seems to be related to lower aggression levels.

Video below has three in a single aquarium where they show minimal problems. It is easy to see when two come together where displays are given that appear to cause one or both to away from each other.

Are the daphnia live or freeze dried? I am trying to push a coldwater daphnia culture to feed Pirate Perch.

Do you feed them for a spell on brine shrimp or go directly to powdered food? I did later with Zebra Danios most of time but had faster growth with the brine shrimp.

The cichlids are a domestic stock able to operate in the range the Red-tailed Sharks are currently kept under. I have bred them and several other species from the same lake. The Rainbow Sharks formed a pair bond? That would be unusual for any cyprinids I know anything about.

Adjustments needed in coming days. A pair of relatively small albino Neolamprologus brichardi in same tank are getting ready to spawn. Tank becoming to tight because of them alone. Will shift Red-tailed Sharks to a 125-gallon tank. Need more light to promote rapid regeneration of biofilm in...

I have a student doing some behavioral work with juvenile Northern Bluegill that may result in some videos of interest to some. Bluegills are more interesting than many think.

Bantam Sunfish http://www.nanfa.org/ac/spawning-raising-bantam-sunfish.pdf Warmouth (co-written with student) https://www.nanfa.org/articles/pdf/Warmouthspawning.pdf Could generate similar with Red Spotted Sunfish and Orange Spotted Sunfish in short order. Trying to keep articles in similar...

Will try to post link to couple of articles. Maybe later create fact sheets that align with those for other species here.

This is a group that I have messed with a lot. Bluegill in particular have occupied my tanks, but done some others too. I have a single female Hand-paint Bluegill. She looks a lot different from the standard Northern Bluegill and the various types of Coppernose Bluegill in the SE USA.

Why not write up an article describing what happened? Am I correct to assume territories abandoned during spawning? Tank I will use is 12 x 6 x 4 ft fiberglass where I can introduce a flush of well water or rainwater. I may also run a pump horizontally to make for a current. In some ways the...

Where did you get information of spawning behavior? Another account indicated spawning occurs in caves or cavities. I can rear spawn in a >2,000-gallon tank near barn and use a couple 500-gallon tanks for same purpose. Spawn induction will not be done until summer when temperature range suitable.

Do any of the scientist / ichthyologist have experience with the breeding and rearing of early life-stage Red-tailed Sharks? So far I can find nothing. I want particulars on spawning and care of larvae. At this point, information of interest to me appears to be proprietary to farmers producing...

Contents of link below appears based on first hand experience. Trying to contact author. https://iere.org/red-tail-shark/

The largest of the Red-tailed Sharks is growing very fast. First hand accounts from people I know have growth all over the place with most indicating slow growth. I am feeding the fish roughly 4X per day which appears optimal for a fish that is more or less a continuous feeder. Will have to be...

Thanks for link. I suspect there is a hump of incompatibility where 1 is better than a small social group that is not sustainable / stable. Past the hump with larger groups maybe sustainable. The approach works well with other species I am familiar with. Will keep you posted on results.

Feeding activity is very interesting. Most effort directed towards biofilm, especially in areas with current. They appear to have capacity to eat a lot. Being chased makes so you do not want to eat for a little while after the chase. If feeding on a quality source with a belly full, then not as...

4.5 to 5 inches depending upon source you read. I think sexual maturity is about 3" based on looks of those I have seen as that is when they start to get more robust.

I have very limited capacity for photographs at moment. First image shows over all tank with LED light source. Biofilm is not being removing for betterment of the Red-tailed Sharks.

About 2 months ago we purchased a single Red-tailed Shark and stocked it by itself into a 29-gallon high. About a month later we purchased a second, but had to separate them with a partition. We want to see interactions so decided to acquire more in an attempt to override an overly simple...
